The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning).
To improve here there is a quest to make the remove callback return void.
In the first step of this quest all drivers are converted to .remove_new()
which already returns void. Eventually after all drivers are converted,
.remove_new() is renamed to .remove().
Before this driver might have returned an error. In this case emit a
warning that tells more about the problem than the generic warning by
the core, and instead of making the remove callback return zero
unconditionally, convert to .remove_new() which is equivalent.

Input: libps2 - do not discard non-ack bytes when controlling LEDs
Upon receiving a PS/2 command the device and controller are supposed to
stop sending normal data (scancodes or movement packets) and instead
immediately start delivering ACK/NAK and command response. Unfortunately
often EC has an output buffer which may contain latched data by the time
the EC receives a command from the host. The kernel used to ignore such
data, but that may cause "stuck" keys if the data dropped happens to be a
break code or a part of a break code. This occasionally happens, for
example, on Chromebooks when the kernel tries to toggle CapsLock LED on
a keyboard while user releases Alt+Search keyboard shortcut.
Fix this by passing the first non-ACK byte to the normal handler for a
handful of PS/2 commands that are expected to be used during normal device
operation (as opposed to probe/configuration time).

result in 0. To correct this shift the strong_magnitude / weak_magnitude

instead.
Secondly the RTP mode that is used by default interprets the values as
signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This

Input: hideep - optionally reset controller work mode to native HiDeep protocol
The HiDeep IST940E touchscreen controller used on the Lenovo Yoga Book X90F
convertible comes up in HID mode by default.
This works well on the X91F Windows model where the touchscreen is
correctly described in ACPI and ACPI takes care of controlling
the reset GPIO and regulators.
But the X90F ships with Android and the ACPI tables on this model don't
describe the touchscreen. Instead this is hardcoded in the vendor kernel.
The vendor kernel uses the touchscreen in native HiDeep 20 (2.0?) protocol
mode and switches the controller to this mode by writing 0 to reg 0x081e.
Adjusting the i2c-hid code to deal with the reset-gpio and regulators on
this non devicetree (but rather broken ACPI) convertible is somewhat tricky
and the native protocol reports ABS_MT_PRESSURE and ABS_MT_TOUCH_MAJOR
which are not reported in HID mode, so it is preferable to use the native
mode.
Add support to the hideep driver to reset the work-mode to the native
HiDeep protocol to allow using it on the Lenovo Yoga Book X90F.
This is guarded behind a new "hideep,force-native-protocol" boolean
property, to avoid changing behavior on other devices.
For the record: I did test using the i2c-hid driver with some quick hacks
and it does work. The I2C-HID descriptor is available from address 0x0020,
just like on the X91F Windows model.
So far the new "hideep,force-native-protocol" property is only used on
x86/ACPI (non devicetree) devs. IOW it is not used in actual devicetree
files. The devicetree-bindings maintainers have requested properties like
these to not be added to the devicetree-bindings, so the new property is
deliberately not added to the existing devicetree-bindings.

The Android Lenovo Yoga Book X90F / X90L uses the same goodix touchscreen
with 9 bytes touch reports for its touch keyboard as the already supported
Windows Lenovo Yoga Book X91F/L, add a DMI match for this to
the nine_bytes_report DMI table.
When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

tpm: disable hwrng for fTPM on some AMD designs
tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address
AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d58db ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address
tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI
table is found. If the firmware vendor includes an invalid log address
we are unable to map from the ACPI memory and tpm_read_log() returns -EIO
which would abort discovery of the eventlog.
Change the return value from -EIO to -ENODEV when acpi_os_map_iomem()
fails to map the event log.
