Remove "bResult" and "tmpchannel" and all tests and assignments that
are related to them in the code of PHY_SwChnl8188E().
"bResult" was always true, therefore its test led to a null statement.
"tmpchannel" was used only to restore "pHalData->CurrentChannel" to its
previous value only if _PHY_SwChnl8192C() was not called; therefore
assign "channel" to "pHalData->CurrentChannel" if and only if
_PHY_SwChnl8192C() is to be executed (and get rid of that temporary

The current_opp is released only when whole OPP table is released,
otherwise it's only marked as removed by dev_pm_opp_remove_table().
Functions like dev_pm_opp_put_clkname() and dev_pm_opp_put_supported_hw()
are checking whether OPP table is empty and it's not if current_opp is
set since it holds the refcount of OPP, this produces a noisy warning
from these functions about busy OPP table. Remove the checks to fix it.

There is no reason to assume that the IRQ rising edge (indicating that
the device start up phase is done) will happen after we request the IRQ.
If the device is already up by the time we request it, the call to
'wait_for_completion_timeout()' will timeout and we will fail the device
probe even though there's nothing wrong.
Fix it by just polling the status register until we get the indication that
the device is up and running. As a side effect of this fix, requesting the
IRQ is also moved to after the setup function.

Commit 41a9ada3e6 ("of/fdt: mark hotpluggable memory") introduced
two (for systems with and without memblock) weak versions of
early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an
architecture-specific version. However, no overrides ever emerged.
Later, commit aca52c3983 ("mm: remove CONFIG_HAVE_MEMBLOCK")
removed the non-memblock version.
Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a
direct call to memblock_mark_hotplug().

Kuniyuki Iwashima says:
====================
This patch set adds BPF iterator support for UNIX domain socket. The first
patch implements it, and the second adds "%c" support for BPF_SEQ_PRINTF().
Thanks to Yonghong Song for the fix [0] for the LLVM code gen. The fix
prevents the LLVM compiler from transforming the loop exit condition '<' to
'!=', where the upper bound is not a constant. The transformation leads
the verifier to interpret it as an infinite loop.
And thanks to Andrii Nakryiko for its workaround [1].

The iterator can output almost the same result compared to /proc/net/unix.
The header line is aligned, and the Inode column uses "%8lu" because "%5lu"
can be easily overflown.

/proc/net/unix uses "%c" to print a single-byte character to escape '\0' in
the name of the abstract UNIX domain socket. The following selftest uses
it, so this patch adds support for "%c". Note that it does not support
wide character ("%lc" and "%llc") for simplicity.

This patch implements the BPF iterator for the UNIX domain socket.
Currently, the batch optimisation introduced for the TCP iterator in the
commit 04c7820b77 ("bpf: tcp: Bpf iter batching and lock_sock") is not
used for the UNIX domain socket. It will require replacing the big lock
for the hash table with small locks for each hash list not to block other
processes.

Usual mix of cleanups and new device support.
Counter
======
Cleanups and refactoring:
* treewide
- Ensure attempts to set invalid modes result in -EINVAL return.
- Rename counter_count_function to counter_function as the middle count
is redundant.
- Standardize error returns when limits are exceeded.
* 104-quad:
- Document the lock.
- Return an error if attempt to set the ceiling value in a mode that
doesn't support it.
* intel-qep
- Drop unused bitops.h include
IIO
===
New device support
* bma255
- Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
interrupt pin and not INT1. Patch set includes enabling use of INT2.
* ingenic_adc
- Add support for JZ4760 and similar and update bindings
- Add support for JZ4760B and update bindings
* rockchip_saradc
- Add support for rk3568 ADC (separate channel array as more channels)
* sgp40 gas sensor used to measure air quality
- New driver including binding and ABI documentation.
Bindings
--------
* Add missing bindings for many DACs where the binding was effectively
implicit due to fallback probe methods in I2C and SPI.

definitely don't want the example to suggest this would be normal.
- Add interrupt-names to allow for cases where only INT2 is connected.
- Sort compatibles
- Merge in very similar bosch,bma180 binding.
New feature
-----------
* Devices only allowed to provide either extended_name or a label for given
channel. If extend_name is used (generally discouraged but can't be
removed as it would be a userspaece ABI change), then the label sysfs
attribute will provide the extended_name. This allows some userspace
parser simplications and hardening.
* hid-sensors-pres
- Add a timestamp channel (either from hardware, or locally filled).
* vcnl3020
- Add periodic sensor mode used to provide IIO events.
Cleanups / minor fixes
----------------------
* core/buffers
- Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
- Move a sanity check earlier to simplify error path.

- tcs3414
- tmp006
* ad5624r
- Fix incorrect handling of a regulator that was preventing use of
internal regulators.
* adjd_s311
- Allocate a buffer as part of iio_priv() structure as maximum size
is small enough, no significant advantage in making it flexible sized.
* bma220
- Make handling of suspend and resume closer to the probe() wrt to the
rather odd interface, that suspend mode is entered by reading a register.
* ep93xx
- Prepare clock before using (part of conversion to CCF)
* fsl-imx25-gcq
- Use local device pointer.
- Adjust handling of platform_get_irq() to not check for 0 as an error.
The function is documented as never returning it.
* hid-sensors
- Use devm_kmemdup() consistently across all drivers to simplify channel
structure allocation management.
* meson-saradc
- Drop BL30 integration on G12A and newer SoCs as not used.
- Whitespace fixes.
* mpu6050
- Add per device type startup times. This avoids an issue with having
to dsicard initial data from gyroscopes when they were still stabilizing.
* rfd77402
- Change from passing private data, to passing i2c_client where only
that is needed, reducing back and forth in pm functions.
* si1145
- Drop pointless continue
* st-sensors
- Cleanup of includes to remove unused and add missing headers that are used.
- Use some devm functions to simplify probe() and remove() - gets us part way
towards a fully device managed driver.
* sx9310
- Switch from of to generic properties to enable ACPI bindings.
* vcnl3020
- Add DMA safe buffer for bulk transfers.
- Drop use of iio_claim_direct() in a driver that has no mode changes.
A local lock is more appropriate.

* rfd77402
- Change from passing private data, to passing i2c_client where only
that is needed, reducing back and forth in pm functions.
* si1145
- Drop pointless continue
* st-sensors
- Cleanup of includes to remove unused and add missing headers that are used.
- Use some devm functions to simplify probe() and remove() - gets us part way
towards a fully device managed driver.
* sx9310
- Switch from of to generic properties to enable ACPI bindings.
* vcnl3020
- Add DMA safe buffer for bulk transfers.
- Drop use of iio_claim_direct() in a driver that has no mode changes.
A local lock is more appropriate.

Pull libnvdimm fixes from Dan Williams:
"A couple of fixes for long standing bugs, a warning fixup, and some
miscellaneous dax cleanups.
The bugs were recently found due to new platforms looking to use the
ACPI NFIT "virtual" device definition, and new error injection
capabilities to trigger error responses to label area requests. Ira's
cleanups have been long pending, I neglected to send them earlier, and
see no harm in including them now. This has all appeared in -next with
no reported issues.
Summary:
- Fix support for NFIT "virtual" ranges (BIOS-defined memory disks)
- Fix recovery from failed label storage areas on NVDIMM devices
- Miscellaneous cleanups from Ira's investigation of
dax_direct_access paths preparing for stray-write protection"

Here is a single revert of a commit that caused problems in 5.14-rc5 for
5.14-rc6. It has been in linux-next almost all week, and has resolved
the issues that were reported on lots of different systems that were not
the platform that the change was originally tested on (gotta love SoC
cores used in multiple devices from multiple vendors...)
