RGB LED
Add a charging_orange_full_green LED trigger and the trigger is based on
led_mc_trigger_event() which can set an RGB LED when the trigger is
triggered. The LED will show orange when the battery status is charging.
The LED will show green when the battery status is full.

Add a new led_mc_set_brightness() function for in kernel color/brightness
changing of multi-color LEDs.
led-class-multicolor can be build as a module and led_mc_set_brightness()
will have the builtin callers, so put led_mc_set_brightness() inside
led-core instead, just like how led_set_brightness() is part of the core
and not of the led-class object.
This also adds a new LED_MULTI_COLOR led_classdev flag to allow
led_mc_set_brightness() to verify that it is operating on a multi-color
LED classdev, avoiding casting the passed in LED classdev to a multi-color
LED classdev, when it actually is not a multi-color LED.

The rtt-upiu packets precede any data-out upiu packets, thus synchronizing
the data input to the device: this mostly applies to write operations, but
there are other operations that requires rtt as well.
There are several rules binding this rtt - data-out dialog, specifically
There can be at most outstanding bMaxNumOfRTT such packets. This might
have an effect on write performance (sequential write in particular), as
each data-out upiu must wait for its rtt sibling.
UFSHCI expects bMaxNumOfRTT to be min(bDeviceRTTCap, NORTT). However, as of
today, there does not appears to be no-one who sets it: not the host
controller nor the driver. It wasn't an issue up to now: bMaxNumOfRTT is
set to 2 after manufacturing, and wasn't limiting the write performance.
UFS4.0, and specifically gear 5 changes this, and requires the device to be
more attentive. This doesn't come free - the device has to allocate more
resources to that end, but the sequential write performance improvement is
significant. Early measurements shows 25% gain when moving from rtt 2 to
9. Therefore, set bMaxNumOfRTT to be min(bDeviceRTTCap, NORTT) as UFSHCI
expects.

This patch implements the "poll" of the "struct file_operations" for BPF
links and introduces a new "poll" operator in the "struct bpf_link_ops". By

A zoned device may have a last sequential write required zone that is
smaller than other zones. However, all tests to check if a zone write
plug write offset exceeds the zone capacity use the same capacity
value stored in the gendisk zone_capacity field. This is incorrect for a
zoned device with a last runt (smaller) zone.
Add the new field last_zone_capacity to struct gendisk to store the
capacity of the last zone of the device. blk_revalidate_seq_zone() and
blk_revalidate_conv_zone() are both modified to get this value when
disk_zone_is_last() returns true. Similarly to zone_capacity, the value
is first stored using the last_zone_capacity field of struct
blk_revalidate_zone_args. Once zone revalidation of all zones is done,
this is used to set the gendisk last_zone_capacity field.
The checks to determine if a zone is full or if a sector offset in a
zone exceeds the zone capacity in disk_should_remove_zone_wplug(),
disk_zone_wplug_abort_unaligned(), blk_zone_write_plug_init_request(),
and blk_zone_wplug_prepare_bio() are modified to use the new helper
functions disk_zone_is_full() and disk_zone_wplug_is_full().
disk_zone_is_full() uses the zone index to determine if the zone being
tested is the last one of the disk and uses the either the disk
zone_capacity or last_zone_capacity accordingly.

There are multiple assertion formatting functions in the `assert.c`
file, which are not covered with tests yet. Implement the KUnit test
for these functions.
The test consists of 11 test cases for the following functions:
1) 'is_literal'
2) 'is_str_literal'
3) 'kunit_assert_prologue', test case for multiple assert types
4) 'kunit_assert_print_msg'
5) 'kunit_unary_assert_format'
6) 'kunit_ptr_not_err_assert_format'
7) 'kunit_binary_assert_format'
8) 'kunit_binary_ptr_assert_format'
9) 'kunit_binary_str_assert_format'
10) 'kunit_assert_hexdump'
11) 'kunit_mem_assert_format'
The test aims at maximizing the branch coverage for the assertion
formatting functions.
As you can see, it covers some of the static helper functions as
well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT'
and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the
corresponding definitions to `assert.h`.
Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to
how it is done for the string stream test.

BNXT_RE_COMP_MASK_UCNTX_HW_RETX_ENABLED was introduced to share the HW
retransmit capability between driver and lib. The main difference in
implementation for HW Retransmit support is the usage of MSN table or
PSN table . When HW retrans is enabled, HW expects MSN table to be
allocated by driver/lib, else PSN table (for older adapters).
FW expose a new field which gives MSN capability. Drivers and libs can
depend on the new field instead of HW Retrasns capability. For
adapters which support HW_RETX feature, MSN table capability will be
set. For older adapters, this value will be 0(to maintain backward
compatibility with older FW).
Rename UAPI just to capture the correct name of the HW capability
that driver/library is interested in. No functional impact even if
older rdma-core is used.

Recent commit 0cfe71f45f42 ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

__dst_negative_advice() does not enforce proper RCU rules when
sk->dst_cache must be cleared, leading to possible UAF.
RCU rules are that we must first clear sk->sk_dst_cache,
then call dst_release(old_dst).
Note that sk_dst_reset(sk) is implementing this protocol correctly,
while __dst_negative_advice() uses the wrong order.
Given that ip6_negative_advice() has special logic
against RTF_CACHE, this means each of the three ->negative_advice()
existing methods must perform the sk_dst_reset() themselves.
Note the check against NULL dst is centralized in
__dst_negative_advice(), there is no need to duplicate
it in various callbacks.
Many thanks to Clement Lecigne for tracking this issue.

We need to fix [e]poll bugs in the following patches,
it makes sense to use a common helper.

Add qcom_smem_bust_hwspin_lock_by_host to enable remoteproc to bust the
hwspin_lock owned by smem. In the event the remoteproc crashes
unexpectedly, the remoteproc driver can invoke this API to try and bust
the hwspin_lock and release the lock if still held by the remoteproc
device.

When a remoteproc crashes or goes down unexpectedly this can result in
a state where locks held by the remoteproc will remain locked possibly
resulting in deadlock. This new API hwspin_lock_bust() allows
hwspinlock implementers to define a bust operation for freeing previously
acquired hwspinlocks after verifying ownership of the acquired lock.

X1E80100 CRD is the first board, which comes with four speakers, so we
still keep fixing and adding missing pieces.
The board has speaker arranged as left front+back and then right
front+back. Using default channel mapping causes front right speaker to
play left back stream.
Adjust the channel maps for frontend DAIs to fix stereo and four-channel
playback.

The AHUB HW modules are interconnected with CIF which are capable of
supporting Channel and Sample bit format conversion. Due to this, the
I2S Client can have different Channel and Sample bit from the hw_params()
and this config is passed from CIF port of I2S DT node which can help to
perform this conversion.
- First change to split simple_fixup_sample_fmt to support returning
sample format value
- Second patch to support Tegra I2S client channel and sample format
programming based on CIF port from DT node.

We've been testing ondemand mode for cachefiles since January, and we're
almost done. We hit a lot of issues during the testing period, and this
patch set fixes some of the issues related to ondemand requests.
The patches have passed internal testing without regression.
The following is a brief overview of the patches, see the patches for
more details.
Patch 1-5: Holding reference counts of reqs and objects on read requests
to avoid malicious restore leading to use-after-free.
Patch 6-10: Add some consistency checks to copen/cread/get_fd to avoid
malicious copen/cread/close fd injections causing use-after-free or hung.
Patch 11: When cache is marked as CACHEFILES_DEAD, flush all requests,
otherwise the kernel may be hung. since this state is irreversible, the
daemon can read open requests but cannot copen.
Patch 12: Allow interrupting a read request being processed by killing
the read process as a way of avoiding hung in some special cases.

When extra warnings are enabled, gcc points out a global variable
definition in a header:
In file included from drivers/cpufreq/amd-pstate-ut.c:29:

This header is only included from two files in the same directory,
and one of them uses only a single definition from it, so clean it
up by moving most of the contents into the driver that uses them,
and making shared bits a local header file.
