[alsa-devel] [PATCH 0/7] ALSA: HD-audio display power fixes

[Takashi Iwai]

Hi,

this patch is about fixing possible HD-audio display power unbalance.
Basically the "fix" is done by refactoring the whole relevant code.
It starts from the Intel HD-audio runtime PM refactoring, followed
by the display PM API change, and lots of code cleanups.

Since it changes the display power API function, it hits both legacy
and ASoC drivers.

The patches are kept in topic/hda-pm-refactor branch of my sound git
tree.  This will be an immutable branch once when merged to for-next,
so that it can be merged to ASoC tree if any conflicting change needs
to be applied.
