sound fixes for 5.8-rc1

Here are last-minute fixes gathered before merge window close;
a few fixes are for the core while the rest majority are driver
fixes.

* PCM locking annotation fixes and the possible self-lock fix
* ASoC DPCM regression fixes with multi-CPU DAI
* A fix for inconsistent resume from system-PM on USB-audio
* Improved runtime-PM handling with multiple USB interfaces
* Quirks for HD-audio and USB-audio
* Hardened firmware handling in max98390 codec
* A couple of fixes for meson

Just as a heads up, we just recently got HDMI audio working on the
Dragonboard 845c (Vinod has patches he's sending out here in the next
few days), but they suddenly stopped working today with the following
error:

I don't know the backgroun again, but would something like the
following make sense?
https://git.linaro.org/people/john.stultz/android-dev.git/commit/?h=dev/db845c-mainline-WIP&id=7e49b248db77b5ed29b2aa278268e77650c75482

It avoids failing completely if playback or capture isn't found.

Can you please try these two patches, I think the problem is that FE 
dailinks are always set to bidirectional, this two patches should fix it.

Once you confirm I can send them to list as fixes.

For the benefit of readers that's "ASoC: soc-pcm: dpcm: fix
playback/capture checks".

That's a small out of tree test patch which has no changelog so I'm not
entirely clear what the intent or motivation is but it looks like the
goal is to change so that we only warn when a link says it supports
playback/capture but some of the DAIs lack the capability instead of
returning an error.  I'm not sure I understand how that helps, it seems
like the link is still misconfigured and we still have a warning which
isn't great?  Surely the issue is that we've flagged the link as
supporting capture when it doesn't?

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

These seem sensible to me, probably worth submitting them even if more
investigation is needed on the original issue.

Indeed the addition of stricter checks will expose cases where the links 
are not well configured, probably for years. The patch "ASoC: soc-pcm: 
dpcm: fix playback/capture checks" did not add those checks, only fixed 
them for the multi-dai case.

I think that those configuration errors are the problem and should be 
fixed as a prerequisite to the removal of the duplication between 
dpcm_playback/dpcm_capture/playback_only/capture_only. it may be painful 
and generate noise for a while, but if we only throw a warning what are 
the odds all those configuration errors will eventually be fixed?

If we need more time for validation on all platforms, then maybe we can 
first relax the check for 5.8-rc1 as suggested by John, but re-add the 
-EINVAL on -next to give a target of 5.9 with all configurations fixed?

Yeah, I'm kind of pessimistic about the likelyhood of people paying
attention to warnings.

I can't help feeling that it'd be postponing the inevitable, but perhaps
I'm being overly pessimistic here.  The change did obviously go in quite
late though so it's not the worst idea if you want to send the patch?
