[alsa-devel] hp_pin was NULL value

alc225_hp_init() ==> it only need to call one time at boot time.
This HP initial code doesn't need to call at resume.
If system boot, HP initial code just need to call it at boot time.
S3 state was not need to call this function.

Sorry!! Maybe I describe it confuse you.

... and I don't understand what's your problem.

Is it about that alc255_hp_init() gets called at resume in addition to the boot time?  If so, this is the intended behavior.
