[PATCH] ALSA: hda/realtek: Add micmute LED quirk for Acer Aspire A515-57

[Giulio Gualtierotti]

The Acer Aspire A515-57 with subsystem ID 1025:1616 and Realtek
ALC256 uses GPIO2 (0x04) for the microphone mute LED. Without a
quirk, the GPIO mask and direction are not configured and the LED
does not follow the microphone mute state.

Reuse ALC256_FIXUP_ACER_SFG16_MICMUTE_LED, which configures GPIO2
as the microphone mute LED.

Tested on an Acer Aspire A515-57 with ALC256 (10ec:0256,
subsystem 1025:1616). GPIO mask and direction are 0x04 and GPIO
data switches between 0x00 and 0x04; the LED device is registered
and follows the microphone mute state.

Applied now.  Thanks.
