[alsa-devel] [PATCH] ASoC: da7219: check SRM lock in trigger callback

See comment #3 in the bug. This is not a GLK specific issue. If I remember
correctly Fletcher found that this was occurring on 2-3 platforms. SST has
the ability to turn on clocks on demand which is why this has not been an
issue previously from what I understand on the bug.

And that is a fair point, we do need to consider other users of the codec.
