w1: omap-hdq: Simplify driver with PM runtime autosuspend
We've had generic code handling module sysconfig and OCP reset registers
for omap variants for many years now and all the drivers really needs to
do is just call runtime PM functions.
Looks like the omap-hdq driver got only partially updated over the years
to use runtime PM, and still has lots of custom PM code left.
We can replace all the custom code for sysconfig, OCP reset, and PM with
just a few lines of runtime PM autosuspend code.
In order to set the device mode properly when pm_runtime_get_sync() is
called during probe, we need to also move parsing of "ti,mode" to happen
earlier before we call pm_runtime_enable().
Since we now disable interrupts lazily in omap_hdq_runtime_suspend(), we
must remove the call to hdq_disable_interrupt() in omap_w1_read_byte().
And we must clear irqstatus calling wait_event_timeout() on it, so let's
add hdq_reset_irqstatus() for that.
Note that the earlier driver specific usage count limit of four seems
completely artificial and should not be an issue in normal use.

But get_user() can't be used with a void pointer, it a

drivers/misc: sram-exec: have the callers of set_memory_*() check the return value
Right now several architectures allow their set_memory_*() family of
functions to fail, but callers may not be checking the return values.
If set_memory_*() returns with an error, call-site assumptions may be
infact wrong to assume that it would either succeed or not succeed at
all. Ideally, the failure of set_memory_*() should be passed up the call
stack, and callers should examine the failure and deal with it.
Need to fix the callers and add the __must_check attribute. They also
may not provide any level of atomicity, in the sense that the memory
protections may be left incomplete on failure. This issue likely has a
few steps on effects architectures:
1) Have all callers of set_memory_*() helpers check the return value.
2) Add __must_check to all set_memory_*() helpers so that new uses do
not ignore the return value.
3) Add atomicity to the calls so that the memory protections aren't
left in a partial state.
This series is part of step 1. Make sram driver check the return value
of set_memory_*().

Pull thread fixes from Christian Brauner:
"This contains a series of patches to fix CLONE_SETTLS when used with
clone3().
The clone3() syscall passes the tls argument through struct clone_args
instead of a register. This means, all architectures that do not
implement copy_thread_tls() but still support CLONE_SETTLS via
copy_thread() expecting the tls to be located in a register argument
based on clone() are currently unfortunately broken. Their tls value
will be garbage.
The patch series fixes this on all architectures that currently define
__ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
that any architecture that enables clone3() in the future is forced to
also implement copy_thread_tls().
My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
split and just have copy_thread_tls() at some point in the not too
distant future (Maybe even renaming copy_thread_tls() back to simply
copy_thread() once the old function is ripped from all arches). This
is dependent now on all arches supporting clone3().
While all relevant arches do that now there are still four missing:
ia64, m68k, sh and sparc. They have the system call reserved, but not
implemented. Once they all implement clone3() we can get rid of
ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
This series also includes a minor fix for the arm64 uapi headers which
caused __NR_clone3 to be missing from the exported user headers.
Unfortunately the series came in a little late especially given that
it touches a range of architectures. Due to the holidays not all arch
maintainers responded in time probably due to their backlog. Will and
Arnd have thankfully acked the arm specific changes.
Given that the changes are straightforward and rather minimal combined
with the fact the that clone3() with CLONE_SETTLS is broken I decided
to send them post rc3 nonetheless"

mtd: spi-nor: Fix the writing of the Status Register on micron flashes
Micron flashes do not support 16 bit writes on the Status Register.
According to micron datasheets, when using the Write Status Register
(01h) command, the chip select should be driven LOW and held LOW until
the eighth bit of the last data byte has been latched in, after which
it must be driven HIGH. If CS is not driven HIGH, the command is not
executed, flag status register error bits are not set, and the write enable
latch remains set to 1. This fixes the lock operations on micron flashes.

fs: move guard_bio_eod() after bio_set_op_attrs
Commit 85a8ce62c2ea ("block: add bio_truncate to fix guard_bio_eod")
adds bio_truncate() for handling bio EOD. However, bio_truncate()
doesn't use the passed 'op' parameter from guard_bio_eod's callers.
So bio_trunacate() may retrieve wrong 'op', and zering pages may
not be done for READ bio.
Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs()
in submit_bh_wbc() so that bio_truncate() can always retrieve correct
op info.
Meantime remove the 'op' parameter from guard_bio_eod() because it isn't
used any more.

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not

When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.
