[alsa-devel] [PATCH RFC 0/4] HDA/i915 jack handling using component

[Takashi Iwai]

Hi,

after the previous discussion ([RFC PATCH 0/2] ALSA: hda - DP MST
audio for Jack support), I thought it'd be even easier to give a
concrete code for further discussion; so here we go, it's a patchset
to implement the jack via audio component.

In the end, I added a new audio component ops to fetch the current
ELD, since the state is unknown at the time the audio driver starts.
The other two patches are just a cleanup.

This series is submitted just as an RFC, basically for a better
understanding, not seriously considered to be merged as is.
(That's why no intel-gfx is Cc'ed yet.)

Note that the i915 patches are applied to the latest Linus tree, while
patch_hdmi.c patch is to my for-linus branch.  The patches are found
in test/hdmi-jack branch of sound git tree.
