[PATCH 0/2] ASoC: hdmi-codec: fix locking issue

From: Jerome Brunet

This patchset fixes the locking issue reported by Russell.

As explained a mutex was used as flag and held while returning to
userspace.

Patch 2 is entirely optional and switches from bit atomic operation
to mutex again. I tend to prefer bit atomic operation in this
particular case but either way should be fine.
