cc4cbd4b4f media: Drop explicit initialization of struct i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

While add it, also remove commas after the sentinel entries.

002a5db9a5 wifi: rtw88: Enable USB RX aggregation for 8822c/8822b/8821c
Enable USB RX aggregation when there is at least 1 Mbps RX or TX
traffic, otherwise disable it.

USB RX aggregation improves the RX speed of RTL8811CU on certain ARM
systems, like the NanoPi NEO Core2. Before: 28 Mbps, after: 231 Mbps.

It also improves the RX speed of RTL8822CU on some x86_64 systems.
Before: ~200 Mbps, after: ~300 Mbps.

The official drivers for these chips use the same logic for SDIO, but
for some reason the SDIO driver in rtw88 always enables RX aggregation,
so this patch only toggles aggregation for USB devices.

RTL8703B is likely not found in USB devices, and RTL8723DU doesn't like
aggregation.

RX aggregation improves the RX speed of RTL8811CU on certain ARM

RTL8822CU on some x86_64 systems.

Currently none of the chips are configured to aggregate frames.

Tested with RTL8822CU, RTL8811CU, and RTL8723DU.

0f683c2cf6 wifi: rtw89: wow: implement PS mode for net-detect
When net-detect is enabled, WoWLAN firmware will periodically
scan until beacon or probe response of configured networks are
received. To reduce power consumption, the FW-IPS mode is
implemented to keep WiFi chip in idle mode between each scan.
The FW-IPS is controlled by WoWLAN firmware to turn of some critical
electrical components, and is different from the original IPS mode
which most electrical components are turned off.

45ae0e8cf8 wifi: rtw89: 8852c: support firmware format up to v1
Driver has supported different WoWLAN reason code by commit 0e52102177
("wifi: rtw89: wow: update WoWLAN reason register for different FW")
since firmware version 0.27.80.0. The old driver can't support two
kinds of WoWLAN reason, so increase firmware format to v1.

Also driver tables of BB and RF registers and power values will be added
into v1 format.

39e8111ce5 Merge branch 'add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt()'
Alan Maguire says:

====================
As previously discussed here [1], long-lived sockets can miss
a chance to set additional callbacks if a sock ops program
was not attached early in their lifetime.  Adding support
to bpf_setsockopt() to set callback flags (and bpf_getsockopt()
to retrieve them) provides other opportunities to enable callbacks,
either directly via a cgroup/setsockopt intercepted setsockopt()
or via a socket iterator.

Patch 1 adds bpf_[get|set]sockopt() support; patch 2 adds testing
for it via a sockops programs, along with verification via a
cgroup/getsockopt program.

Changes since v1 [2]:

- Removed unneeded READ_ONCE() (Martin, patch 1)
- Reworked sockopt test to leave existing tests undisturbed while adding
  test_nonstandard_opt() test to cover the TCP_BPF_SOCK_OPS_CB_FLAGS
  case; test verifies that value set via bpf_setsockopt() is what we
  expect via a call to getsockopt() which is caught by a
  cgroup/getsockopt program to provide the flags value (Martin, patch 2)
- Removed unneeded iterator test (Martin)

3882dccf48 bpf/bpf_get,set_sockopt: add option to set TCP-BPF sock ops flags
Currently the only opportunity to set sock ops flags dictating
which callbacks fire for a socket is from within a TCP-BPF sockops
program.  This is problematic if the connection is already set up
as there is no further chance to specify callbacks for that socket.
Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_setsockopt() and bpf_getsockopt()
to allow users to specify callbacks later, either via an iterator
over sockets or via a socket-specific program triggered by a
setsockopt() on the socket.

344576fa6a sched_ext: Improve logging around enable/disable
sched_ext currently doesn't generate messages when the BPF scheduler is
enabled and disabled unless there are errors. It is useful to have paper
trail. Improve logging around enable/disable:

- Generate info messages on enable and non-error disable.

- Update error exit message formatting so that it's consistent with
  non-error message. Also, prefix ei->msg with the BPF scheduler's name to
  make it clear where the message is coming from.

- Shorten scx_exit_reason() strings for SCX_EXIT_UNREG* for brevity and
  consistency.

v2: Use pr_*() instead of KERN_* consistently. (David)

991ef53a48 sched_ext: Make scx_rq_online() also test cpu_active() in addition to SCX_RQ_ONLINE
scx_rq_online() currently only tests SCX_RQ_ONLINE. This isn't fully correct
- e.g. consume_dispatch_q() uses task_run_on_remote_rq() which tests
scx_rq_online() to see whether the current rq can run the task, and, if so,
calls consume_remote_task() to migrate the task to @rq. While the test
itself was done while locking @rq, @rq can be temporarily unlocked by
consume_remote_task() and nothing prevents SCX_RQ_ONLINE from going offline
before the migration takes place.

To address the issue, add cpu_active() test to scx_rq_online(). There is a
synchronize_rcu() between cpu_active() being cleared and the rq going
offline, so if an on-going scheduling operation sees cpu_active(), the
associated rq is guaranteed to not go offline until the scheduling operation
is complete.

72763ea3d4 sched_ext: Fix unsafe list iteration in process_ddsp_deferred_locals()
process_ddsp_deferred_locals() executes deferred direct dispatches to the
local DSQs of remote CPUs. It iterates the tasks on
rq->scx.ddsp_deferred_locals list, removing and calling
dispatch_to_local_dsq() on each. However, the list is protected by the rq
lock that can be dropped by dispatch_to_local_dsq() temporarily, so the list
can be modified during the iteration, which can lead to oopses and other
failures.

Fix it by popping from the head of the list instead of iterating the list.

ASoC: tas*: Fix up GPIO usage
Merge series from Linus Walleij <linus.walleij@linaro.org>:

The TI TAS drivers use some legacy GPIO code and headers,
this series fixes it up.

The TAS2781 is a special case since it adds a handful of
lines of deviating code to reconfigure a GPIO line for
IRQ mode and then never actually use the IRQ obtained in
the code. Is the line used by autonomous hardware? I'm
puzzled by this.

Anyways the patch suggest how to solve this properly by
fixing the parent irqchip and I'm happy to help.

e422c0bfd9 drm/xe: fix WA 14018094691
This WA is applied while initializing the media GT, but it a primary
GT WA (because it modifies a register on the primary GT), so the XE_WA
macro is returning false even when the WA should be applied.
Fix this by using the primary GT in the macro.

Note that this WA only applies to PXP and we don't yet support that in
Xe, so there are no negative effects to this bug, which is why we didn't
see any errors in testing.

v2: use the primary GT in the macro instead of marking the WA as
platform-wide (Lucas, Matt).

599c19397b perf callchain: Fix stitch LBR memory leaks
The 'struct callchain_cursor_node' has a 'struct map_symbol' whose maps
and map members are reference counted. Ensure these values use a _get
routine to increment the reference counts and use map_symbol__exit() to
release the reference counts.

Do similar for 'struct thread's prev_lbr_cursor, but save the size of
the prev_lbr_cursor array so that it may be iterated.

Ensure that when stitch_nodes are placed on the free list the
map_symbols are exited.

Fix resolve_lbr_callchain_sample() by replacing list_replace_init() to
list_splice_init(), so the whole list is moved and nodes aren't leaked.

A reproduction of the memory leaks is possible with a leak sanitizer
build in the perf report command of:

  ```
  $ perf record -e cycles --call-graph lbr perf test -w thloop
  $ perf report --stitch-lbr
  ```

b3f5620f76 bcachefs fixes for 6.11-rc3
Assorted little stuff:
 - lockdep fixup for lockdep_set_notrack_class()
 - we can now remove a device when using erasure coding without
   deadlocking, though we still hit other issues
 - the "allocator stuck" timeout is now configurable, and messages are
   ratelimited; default timeout has been increased from 10 seconds to 30
