sound(4): Apply mixer patches in 13.0-RELEASE

[christos]

Summary

I've concentrated all the kernel patches we've made for the mixer here.
Having these patches available in 13.0-RELEASE can be useful for
people who want to try out the new mixer features on their
system without upgrading to 14.0 or compiling a 13-STABLE kernel.

Bump.

Hi,

I think all of this will be part of the coming 13.1! So let's just abandon this one?

--HPS

Since these are just the kernel patches, would it break anything if we push them in 13.0-RELEASE as well?

[• hselasky]

Technically no, but I worried about some unknown side effects.

But why do you want to push to 13.0 when 13.1 will be out in not too long?

[christos]

Mostly for completeness, but we can abandon it if 13.1 is close to release.

[• hselasky]

Current plan is to release 13.1 April 26, 2022 .

One month :-)

Alright then, we can abandon it!
