ALSA: hda - Proper power-map toggling for input pins
The current code overrides the event type on input pins always to PWR_EVENT. Although this still works (PWR_EVENT and INSERT_EVENT are handled samely), it'd be better to avoid such overrides. Also, currently the unsol events are registered even for fixed pins which will never raise the pin-detection event. This patch fixes both issues. Signed-off-by: Takashi Iwai <tiwai@suse.de>
