commit 693abe11aa6b27aed6eb8222162f8fb986325cef upstream.
Fix hp_pin always no value.
[More notes on the changes:
The hp_pin value that is referred in alc294_hp_init() is always zero at the moment the function gets called, hence this is actually useless as in the current code.
And, this kind of init sequence should be called from the codec init callback, instead of the parser function. So, the first fix in this patch to move the call call into its own init_hook.
OTOH, this function is needed to be called only once after the boot, and it'd take too long for invoking at each resume (where the init callback gets called). So we add a new flag and invoke this only once as an additional fix.
The one case is still not covered, though: S4 resume. But this change itself won't lead to any regression in that regard, so we leave S4 issue as is for now and fix it later. -- tiwai ]
