ASoC: Fixes for v6.18

A moderately large collection of driver specific fixes, plus a few new
quirks and device IDs. The NAU8821 changes are a little large but more
in mechanical ways than in ways that are complex.

Merge tag 'bpf-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

- Support pulling non-linear xdp data with bpf_xdp_pull_data() kfunc
(Amery Hung)

Applied as a stable branch in bpf-next and net-next trees.

- Support reading skb metadata via bpf_dynptr (Jakub Sitnicki)

Also a stable branch in bpf-next and net-next trees.

the verifier (Eduard Zingerman)

This is a significant change in the verification logic. More details,
motivation, long term plans are in the cover letter/merge commit.

Merge branch 'allow-struct_ops-to-create-map-id-to'

Amery Hung says:

====================
This patchset allows struct_ops implementors to get map id from kdata in
reg(), unreg() and update() so that they create an id to struct_ops
instance mapping. This in turn allows struct_ops kfuncs to refer to the
calling instance without passing a pointer to the struct_ops. The selftest
provides an end-to-end example.

Some struct_ops users extend themselves with other bpf programs, which
also need to call struct_ops kfuncs. For example, scx_layered uses
syscall bpf programs as a scx_layered specific control plane and uses
tracing programs to get additional information for scheduling [0].
The kfuncs may need to refer to the struct_ops instance and perform
jobs accordingly. To allow calling struct_ops kfuncs referring to
specific instances from different program types and context (e.g.,
struct_ops, tracing, async callbacks), the traditional way is to pass
the struct_ops pointer to kfuncs.

This patchset provides an alternative way, through a combination of
bpf map id and global variable. First, a struct_ops implementor will
use the map id of the struct_ops map as the id of an instance. Then,
it needs to maintain an id to instance mapping: inserting a new mapping
during reg() and removing it during unreg(). The map id can be acquired
by calling bpf_struct_ops_id().

v1 -> v2
Add bpf_struct_ops_id() instead of using bpf_struct_ops_get()

selftests/bpf: Test multi_st_ops and calling kfuncs from different programs

Test multi_st_ops and demonstrate how different bpf programs can call
a kfuncs that refers to the struct_ops instance in the same source file
by id. The id is defined as a global vairable and initialized before
attaching the skeleton. Kfuncs that take the id can hide the argument
with a macro to make it almost transparent to bpf program developers.

The test involves two struct_ops returning different values from
.test_1. In syscall and tracing programs, check if the correct value is
returned by a kfunc that calls .test_1.
