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: security: add abstraction for secctx

Add an abstraction for viewing the string representation of a security
context.

This is needed by Rust Binder because it has a feature where a process
can view the string representation of the security context for incoming
transactions. The process can use that to authenticate incoming
transactions, and since the feature is provided by the kernel, the
process can trust that the security context is legitimate.

This abstraction makes the following assumptions about the C side:
* When a call to `security_secid_to_secctx` is successful, it returns a
pointer and length. The pointer references a byte string and is valid
for reading for that many bytes.
* The string may be referenced until `security_release_secctx` is
called.
* If CONFIG_SECURITY is set, then the three methods mentioned in
rust/helpers are available without a helper. (That is, they are not a
#define or `static inline`.)
