Subject: HID: elan: Set default_trigger for the mute LED
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=2601371e1082ca30577556d381afacc11a11157b;p=uclinux-h8%2Flinux.git

HID: elan: Set default_trigger for the mute LED

The mute LED should be automatically turned on/off based
on the audio-card's mixer settings.

Add the standardized default-trigger name for this, so that the alsa
code can turn the LED on/off as appropriate (on supported audio cards).
