ASoC: Fixes for v7.0
This is two week's worth of fixes and quirks so it's a bit larger than you might expect, there's nothing too exciting individually and nothing in core code.

Pull io_uring fixes from Jens Axboe:
- Fix an inverted true/false comment on task_no_new_privs, from the BPF filtering changes merged in this release
- Use the migration disabling way of running the BPF filters, as the io_uring side doesn't do that already
- Fix an issue with ->rings stability under resize, both for local task_work additions and for eventfd signaling
- Fix an issue with SQE mixed mode, where a bounds check wasn't correct for having a 128b SQE
- Fix an issue where a legacy provided buffer group is changed to to ring mapped one while legacy buffers from that group are in flight

io_uring: ensure ctx->rings is stable for task work flags manipulation
If DEFER_TASKRUN | SETUP_TASKRUN is used and task work is added while the ring is being resized, it's possible for the OR'ing of IORING_SQ_TASKRUN to happen in the small window of swapping into the new rings and the old rings being freed.
Prevent this by adding a 2nd ->rings pointer, ->rings_rcu, which is protected by RCU. The task work flags manipulation is inside RCU already, and if the resize ring freeing is done post an RCU synchronize, then there's no need to add locking to the fast path of task work additions.
Note: this is only done for DEFER_TASKRUN, as that's the only setup mode that supports ring resizing. If this ever changes, then they too need to use the io_ctx_mark_taskrun() helper.

Merge tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull io_uring updates from Jens Axboe:
- Clean up the IORING_SETUP_R_DISABLED and submitter task checking, mostly just in preparation for relaxing the locking for SINGLE_ISSUER in the future.
- Improve IOPOLL by using a doubly linked list to manage completions.
Previously it was singly listed, which meant that to complete request N in the chain 0..N-1 had to have completed first. With a doubly linked list we can complete whatever request completes in that order, rather than need to wait for a consecutive range to be available. This reduces latencies.
- Improve the restriction setup and checking. Mostly in preparation for adding further features on top of that. Coming in a separate pull request.
- Split out task_work and wait handling into separate files. These are mostly nicely abstracted already, but still remained in the io_uring.c file which is on the larger side.
- Use GFP_KERNEL_ACCOUNT in a few more spots, where appropriate.
- Ensure even the idle io-wq worker exits if a task no longer has any rings open.
- Add support for a non-circular submission queue.
By default, the SQ ring keeps moving around, even if only a few entries are used for each submission. This can be wasteful in terms of cachelines.
If IORING_SETUP_SQ_REWIND is set for the ring when created, each submission will start at offset 0 instead of where we last left off doing submissions.
- Various little cleanups
