ALSA: hda - Fix mute-LED GPIO pin for HP dv series
Old HP dv series seem to use the GPIO pin 0 for controlling the mute LED although the pin is a large package, where the newer models use GPIO 3 in such a case. For fixing the regression from the previous kernels, set spec->gpio_led statically for these model quirks. Signed-off-by: Takashi Iwai <tiwai@suse.de>
