ALSA: hda/realtek - Fixed Speaker Mute LED for HP EliteBoard G1a platform
On the HP EliteBoard G1a platform (models without a headphone jack).
the speaker mute LED failed to function. The Sysfs ctl-led info showed
empty values because the standard LED registration couldn't correctly
bind to the master switch.
Adding this patch will fix and enable the speaker mute LED feature.
