ALSA: hda - Control SPDIF out pin on MacBookPro 11,2
The SPDIF output MBP11,2 requires the pin control to be set/cleared for turning on/off the optical SPDIF. The red light turns off only when the corresponding pin control is cleared (or powered to D3). Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=64401 Signed-off-by: Takashi Iwai <tiwai@suse.de>
