Takashi Iwai 369db2a91d ALSA: hda: intel: Allow repeatedly probing on codec configuration errors
[ Upstream commit c0f1886de7 ]

It seems that a few recent AMD systems show the codec configuration
errors at the early boot, while loading the driver at a later stage
works magically.  Although the root cause of the error isn't clear,
it's certainly not bad to allow retrying the codec probe in such a
case if that helps.

This patch adds the capability for retrying the probe upon codec probe
errors on the certain AMD platforms.  The probe_work is changed to a
delayed work, and at the secondary call, it'll jump to the codec
probing.

Note that, not only adding the re-probing, this includes the behavior
changes in the codec configuration function.  Namely,
snd_hda_codec_configure() won't unregister the codec at errors any
longer.  Instead, its caller, azx_codec_configure() unregisters the
codecs with the probe failures *if* any codec has been successfully
configured.  If all codec probe failed, it doesn't unregister but let
it re-probed -- which is the most case we're seeing and this patch
tries to improve.

Even if the driver doesn't re-probe or give up, it will go to the
"free-all" error path, hence the leftover codecs shall be disabled /
deleted in anyway.
