ASoC: Fixes for v6.13

A few small fixes for v6.13, all system specific - the biggest thing is
the fix for jack handling over suspend on some Intel laptops.

Pull vfs rust file abstractions from Christian Brauner:
"This contains the file abstractions needed by the Rust implementation
of the Binder driver and other parts of the kernel.

Let's treat this as a first attempt at getting something working but I
do expect the actual interfaces to change significantly over time.
Simply because we are still figuring out what actually works. But
there's no point in further theorizing. Let's see how it holds up with
actual users"

Rust Binder mu

rust: cred: add Rust abstraction for `struct cred`

Add a wrapper around `struct cred` called `Credential`, and provide
functionality to get the `Credential` associated with a `File`.

Rust Binder must check the credentials of processes when they attempt to
perform various operations, and these checks usually take a
`&Credential` as parameter. The security_binder_set_context_mgr function
would be one example. This patch is necessary to access these security_*
methods from Rust.

This Rust abstraction makes the following assumptions about the C side:
* `struct cred` is refcounted with `get_cred`/`put_cred`.
* It's okay to transfer a `struct cred` across threads, that is, you do
not need to call `put_cred` on the same thread as where you called
`get_cred`.
* The `euid` field of a `struct cred` never changes after
initialization.
* The `f_cred` field of a `struct file` never changes after
initialization.
