All of the changes in the patches look good to me, as the return value
seems not to be so effective for a long time (15 years or more) and
expected so for future.

One of my concern is that we are mostly in the last week for v6.3
development. When taking influence of the changes into account, it
would be possible to postpone to v6.4 development. But it's up to the
maintainer.

A small nitpicking. I think you use Linus' tree or so:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=05ecb680708a

Because the hash is not reachable from the branch for next merge window on
the tree of sound subsystem upstream:
https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?h=for-next&id=05ecb680708a

I guess it is safer to use his tree as your work-base, even
if the three patches can be applied to it as is (fortunately).
