ASoC: amd: acp: Fix Kconfig dependencies for SND_SOC_ACPI_AMD_SDCA_QUIRKS
Fix the following kconfig warning reported by the kernel test robot:
kismet: WARNING: unmet direct dependencies detected for
SND_SOC_ACPI_AMD_SDCA_QUIRKS when selected by SND_SOC_ACPI_AMD_MATCH
Depends on [n]: SOUND [=y] && SND [=y] && SND_SOC [=y] &&
ACPI [=y] && SND_SOC_SDCA [=n]
Selected by [y]:
- SND_SOC_ACPI_AMD_MATCH [=y] && SOUND [=y] && SND [=y] &&
SND_SOC [=y]
The issue occurs because SND_SOC_ACPI_AMD_SDCA_QUIRKS depends on
SND_SOC_SDCA, which may be disabled, causing unmet dependency warnings.
Fix this by adjusting the Kconfig dependency logic accordingly.

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also disallows force-threading of the primary handler and the
irq-core will warn about this.
Remove IRQF_ONESHOT from irqflags.

ASoC: SDCA: Add NO_DIRECT_COMPLETE flag to class driver
The SDCA class driver currently expects the device will be fully powered
down on system suspend but not on runtime suspend. This is typically
required as when audio is not active (ie. runtime suspend) jack detect
is expected to still function, but when the whole system is hibernated
there is no need to recognise audio jack events. This means the class
driver needs to always be informed of a system suspend, so the direct
complete optimisation (where PM will skip calling system suspend if the
device is runtime suspended) is not appropriate for the SDCA class
driver.
Add the NO_DIRECT_COMPLETE flag to prevent this optimisation from
running against this driver.

ASoC: cs35l56: Add support for new Dell laptops
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
On new Dell models the driver must read a UEFI variable to get a
variant identifier for the audio hardware. Without this, the driver
cannot know which firmware file to load to the amps.
ASoC: cs35l56: Add KUnit testing of cs35l56_set_fw_suffix()
Add a new KUnit test for testing the creation of firmware name
qualifiers in the cs35l56 driver. The initial set of test cases
are for cs35l56_set_fw_suffix().
ASoC: cs-amp-lib: Add a Kconfig symbol for enabling test hooks
Add Kconfig symbol CONFIG_SND_SOC_CS_AMP_LIB_TEST_HOOKS to enable
calling into functions that would normally abort because of missing
EFI functionality. Before this the code paths were only enabled if
the KUnit test for cs-amp-lib was enabled.
This change allows KUnit tests for clients of cs-amp-lib to install
redirection hooks in cs-amp-lib.
Adds test cases for getting a Dell SSIDExV2 string by calling
cs_amp_devm_get_vendor_specific_variant_id().
This is a fairly simple test harness, the redirected call to
cs_amp_get_efi_variable() returns a test string to simulate
reading a string from UEFI. The returned string should be
the second field in the SSIDExV2 string (if valid).
ASoC: cs35l56: Use vendor-specific qualifier in firmware file search
If cs_amp_devm_get_vendor_specific_variant_id() returns a string, use it
as part of the firmware filename. If this firmware isn't found, fall back
to the standard firmware name.
This re-uses the fwf_suffix fallback mechanism that was introduced in
commit e5d5b3aebdc8 ("ASoC: cs35l56: Use SoundWire address as alternate
firmware suffix on L56 B0").
This is for handling vendors that use the same PCI SSID on systems with
various audio hardware and have a custom vendor-specific way to identify
the hardware variant.
This is currently used on Dell laptops. Dell create a UEFI variable that
indicates varations to the base hardware. This variance can be any part
of the hardware (not necessarily affecting the audio). It would be
impractical to publish many aliases for the same firmware files to match
every possible variance to that base hardware. Hence the fallback to the
standard firmware name. This allows alternate firmware files to be
published only for variants that need it. For all other variants the
fallback will load the firmware for the base SSID.
This is not done for CS35L56 B0 because the fallback mechanism is already
used for a different purpose for these parts. None of the products with
the older L56 B0 silicon revision need the additional vendor-specific
descriptor.
For SoundWire the resulting firmware searches with a variant descriptor
will be:
1. cs35l??-dsp1-misc-SSID-VARIANT-l?u?.wmfw
2. cs35l??-dsp1-misc-SSID-VARIANT.wmfw
3. cs35l??-dsp1-misc-SSID-VARIANT-l?u?.bin
4. cs35l??-dsp1-misc-SSID-VARIANT.bin
If this doesn't find a wmfw and bin file it will then fallback to:
5. cs35l??-dsp1-misc-SSID-l?u?.wmfw
6. cs35l??-dsp1-misc-SSID.wmfw
7. cs35l??-dsp1-misc-SSID-l?u?.bin
8. cs35l??-dsp1-misc-SSID.bin
With the typical published firmware names and qualifiers (a single wmfw but
amp-specific bin file) this will load either:
cs35l??-dsp1-misc-SSID-VARIANT.wmfw
and cs35l??-dsp1-misc-SSID-VARIANT-l?u?.bin
or
cs35l??-dsp1-misc-SSID.wmfw
and cs35l??-dsp1-misc-SSID-l?u?.bin
For non-Soundwire (I2S/TDM) systems the searches and fallbacks are
as above except that the "l?u?" component of the name is instead the
ALSA name prefix, usually of the form "AMPn".
ASoC: cs-amp-lib: Support Dell SSIDExV2 UEFI variable
Add a function cs_amp_devm_get_vendor_specific_variant_id() to return
a vendor-specific hardware identifier string (if there is one) and use
it to fetch an identifier from Dell SSIDExV2 UEFI variable content.
Dell use the same PCI SSID on multiple products that might have different
audio hardware and thus need different firmware for the amplifier DSP.
The SSIDExV2 string contains additional system identifiers, and the
second field is a 2-character audio hardware identifier.
There are older Dell models with Cirrus Logic amplifiers that have the
SSIDExV2 UEFI variable but do not have the 2-character audio ID in the
second field. The SSIDExV2 is ignored if the second field is not
2 characters.

ext4: fix ext4_tune_sb_params padding
The padding at the end of struct ext4_tune_sb_params is architecture
specific and in particular is different between x86-32 and x86-64,
since the __u64 member only enforces struct alignment on the latter.
This shows up as a new warning when test-building the headers with
-Wpadded:
include/linux/ext4.h:144:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded]
All members inside the structure are naturally aligned, so the only
difference here is the amount of padding at the end. Make the padding
explicit, to have a consistent sizeof(struct ext4_tune_sb_params) of
232 on all architectures and avoid adding compat ioctl handling for
EXT4_IOC_GET_TUNE_SB_PARAM/EXT4_IOC_SET_TUNE_SB_PARAM.
This is an ABI break on x86-32 but hopefully this can go into 6.18.y early
enough as a fixup so no actual users will be affected. Alternatively, the
kernel could handle the ioctl commands for both sizes (232 and 228 bytes)

attempts to allocate hardware PMU counters for the leader, sibling
events and the new event being added.
This is incorrect for mixed-type groups. If a PERF_TYPE_SOFTWARE event
is part of the group, the current code still tries to allocate a hardware

cause spurious allocation failures.
Fix this by only allocating PMU counters for hardware events during group

xhci: sideband: don't dereference freed ring when removing sideband endpoint
xhci_sideband_remove_endpoint() incorrecly assumes that the endpoint is
running and has a valid transfer ring.
Lianqin reported a crash during suspend/wake-up stress testing, and
found the cause to be dereferencing a non-existing transfer ring
'ep->ring' during xhci_sideband_remove_endpoint().
The endpoint and its ring may be in unknown state if this function
is called after xHCI was reinitialized in resume (lost power), or if
device is being re-enumerated, disconnected or endpoint already dropped.
Fix this by both removing unnecessary ring access, and by checking
ep->ring exists before dereferencing it. Also make sure endpoint is
running before attempting to stop it.
Remove the xhci_initialize_ring_info() call during sideband endpoint
removal as is it only initializes ring structure enqueue, dequeue and
cycle state values to their starting values without changing actual
hardware enqueue, dequeue and cycle state. Leaving them out of sync
is worse than leaving it as it is. The endpoint will get freed in after
this in most usecases.
If the (audio) class driver want's to reuse the endpoint after offload
then it is up to the class driver to ensure endpoint is properly set up.

Pull ftrace fix from Steven Rostedt:
- Fix allocation accounting on boot up
The ftrace records for each function that ftrace can attach to is
done in a group of pages. At boot up, the number of pages are
calculated and allocated. After that, the pages are filled with data.
It may allocate more than needed due to some functions not being
recorded (because they are unused weak functions), this too is
recorded.
After the data is filled in, a check is made to make sure the right
number of pages were allocated. But this was off due to the
assumption that the same number of entries fit per every page.
Because the size of an entry does not evenly divide into PAGE_SIZE,
there is a rounding error when a large number of pages is allocated
to hold the events. This causes the check to fail and triggers a
warning.
Fix the accounting by finding out how many pages are actually
allocated from the functions that allocate them and use that to see
if all the pages allocated were used and the ones not used are
properly freed.

From discussion with Juri and Luca, the purpose of this clause was to
deal with tasks new to DL and all those sites will have MOVE set (as
well as CLASS, but MOVE is move conservative at this point).
Per the previous patches MOVE is audited to always run the balance
callbacks, so switch enqueue_dl_entity() to use MOVE for this case.

sched: Deadline has dynamic priority
While FIFO/RR have static priority, DEADLINE is a dynamic priority
scheme. Notably it has static priority -1. Do not assume the priority
doesn't change for deadline tasks just because the static priority
doesn't change.
This ensures DL always sees {DE,EN}QUEUE_MOVE where appropriate.

sched: Audit MOVE vs balance_callbacks
The {DE,EN}QUEUE_MOVE flag indicates a task is allowed to change
priority, which means there could be balance callbacks queued.
Therefore audit all MOVE users and make sure they do run balance
callbacks before dropping rq-lock.

sched/deadline: Avoid double update_rq_clock()
When setup_new_dl_entity() is called from enqueue_task_dl() ->
enqueue_dl_entity(), the rq-clock should already be updated, and
calling update_rq_clock() again is not right.
Move the update_rq_clock() to the one other caller of
setup_new_dl_entity(): sched_init_dl_server().

Meaning get_prio_dl() ought to update current and return an up-to-date
