[alsa-devel] [PATCH] ALSA: hda - Always call standard unsolicited event

[David Henningsson]

With the model parsers out of the way, we have no custom unsol
events to worry about, we can therefore simplify the code.

In addition, this fixes a bug on the ASUS TC710, which has only
a headphone jack and a mic jack, but no internal mic or speakers.
Therefore the unsol_event pointer was not set, and as a result,
the jack kcontrols were not correctly updated.
