The offset variable is checked by at91_rtc_readalarm(), but this check
is unnecessary because the previous check knew that the value of this
variable was not 0.
This removes that unnecessary offset variable checks.

The STM32MP1 RTC may have 2 clocks, the pclk and the rtc_ck.
If clk_prepare_enable() fails for the second clock (rtc_ck) we must only
call clk_disable_unprepare() for the first clock (pclk) but currently we
call it on both leading to a WARN:

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

The scnprintf() function silently truncates the printf() and returns
the number bytes that it was able to copy (not counting the NUL
terminator). Thus, the highest value it can return here is
"NAME_SIZE - 1" and the overflow check is dead code. Fix this by
using the snprintf() function which returns the number of bytes that
would have been copied if there was enough space and changing the
condition from "> NAME_SIZE" to ">= NAME_SIZE".

Congatec's QMX6 system on module (SoM) uses a m41t62 as RTC. The
modules SQW clock output defaults to 32768 Hz. This behaviour is
used to provide the i.MX6 CKIL clock. Once the RTC driver is probed,
the clock is disabled and all i.MX6 functionality depending on
the 32 KHz clock has undefined behaviour. For example when using
the hardware watchdog the system will likely do arbitrary reboots.
Referencing the m41t62 directly results in a deadlock. The kernel
will see, that i.MX6 system clock needs the RTC clock and do probe
deferral. But the i.MX6 I2C module never becomes usable without the
i.MX6 CKIL clock and thus the RTC's clock will not be probed. So
from the kernel's perspective this is a chicken-and-egg problem.
Technically everything is fine by not touching anything, since
the RTC clock correctly enables the clock on reset (i.e. on
battery backup power loss) and also the bootloader enables it
in case an something (e.g. an unpatched kernel) disabled this
incorrectly.
A workaround for this issue is describing the square wave pin
as fixed-clock, which is registered early and basically how
this pin is used on the i.MX6.

The added Kconfig dependency is slightly incorrect, which can
lead to a link failure when the watchdog is a loadable module:
arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_set_rtc_based_timers':
rtc-bd70528.c:(.text+0x6cc): undefined reference to `bd70528_wdt_set'

arm-linux-gnueabi-ld: rtc-bd70528.c:(.text+0x1030): undefined reference to `bd70528_wdt_unlock'
The problem is that it allows to be built-in if MFD_ROHM_BD71828
is built-in, even when the watchdog is a loadable module.
Rework this so that having the watchdog as a loadable module always
forces the rtc to be a module as well instead of built-in,
regardless of bd71828.

warns about it:

- Prevent PSI state corruption when schedule() races with cgroup move. A
recent commit combined two PSI callbacks to reduce the number of cgroup
tree updates, but missed that schedule() can drop rq::lock for load
balancing, which opens the race window for cgroup_move_task() which then
observes half updated state. The fix is to solely use task::ps_flags
instead of looking at the potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding division
which can lead to an off-by-one error exceeding the buckets array size.
- Prevent unfairness caused by missing load decay when a task is attached

Pull scheduler fixes from Thomas Gleixner:
"A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup
move.
A recent commit combined two PSI callbacks to reduce the number of
cgroup tree updates, but missed that schedule() can drop rq::lock
for load balancing, which opens the race window for
cgroup_move_task() which then observes half updated state.
The fix is to solely use task::ps_flags instead of looking at the
potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding
division which can lead to an off-by-one error exceeding the
buckets array size.
- Prevent unfairness caused by missing load decay when a task is
attached to a cfs runqueue.
The old load of the task was attached to the runqueue and never
removed. Fix it by enforcing the load update through the hierarchy
for unthrottled run queue instances.
- A documentation fix fot the 'sched_verbose' command line option"

- Two fixes for the futex syscall related to the timeout handling.
FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
it's not set the time namespace adjustment for clock MONOTONIC is
applied wrongly.
FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
always a relative timeout.
- Cleanups in the futex syscall entry points which became obvious when
the two timeout handling bugs were fixed.
- Cleanup of queued_write_lock_slowpath() as suggested by Linus
- Fixup of the smp_call_function_single_async() prototype

intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().
End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer. gcc-11 correctly warns
about this case:

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.
There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use

Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

Merge tag 'powerpc-5.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates and fixes from Michael Ellerman:
"A bit of a mixture of things, tying up some loose ends.
There's the removal of the nvlink code, which dependend on a commit in
the vfio tree. Then the enablement of huge vmalloc which was in next
for a few weeks but got dropped due to conflicts. And there's also a
few fixes.
Summary:
- Remove the nvlink support now that it's only user has been removed.
- Enable huge vmalloc mappings for Radix MMU (P9).
- Fix KVM conversion to gfn-based MMU notifier callbacks.
- Fix a kexec/kdump crash with hot plugged CPUs.
- Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR.
- Restore alphabetic order of the selects under CONFIG_PPC.
Thanks to: Christophe Leroy, Christoph Hellwig, Nicholas Piggin,
Sandipan Das, and Sourabh Jain"

In the SMB3/SMB3.1.1 negotiate protocol request, we are supposed to
advertise CAP_MULTICHANNEL capability when establishing multiple
channels has been requested by the user doing the mount. See MS-SMB2
sections 2.2.3 and 3.2.5.2
Without setting it there is some risk that multichannel could fail
if the server interpreted the field strictly.
