ALSA: hda: intel: Allow repeatedly probing on codec configuration errors
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.
