From 12dde4c6d6e9092cf63094e84dc1fe4e505dd6d0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 5 Dec 2008 13:09:27 +0100 Subject: 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.
