Subject: [PATCH] ALSA: hda/realtek - Avoid bogus HP-pin assignment
commit 5fe6e0151dbd969f5fbcd94d05c968b76d76952b upstream.
When the headphone pin is assigned as primary output to line_out_pins[],
the automatic HP-pin assignment by ASSID must be suppressed. Otherwise
a wrong pin might be assigned to the headphone and breaks the auto-mute.
