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.
