ALSA: hda - Assign unsol tags dynamically in patch_sigmatel.c
Since we need to handle many unsolicited events assigned to different widgets, allocate the event dynamically using the existing events array, and use the tag appropriately instead of combination of fixed number and widget nid. (Note that widget nid can be over 4 bits!) Also, replaced the call of unsol_event handler with a dedicated function to be more readable. Signed-off-by: Takashi Iwai <tiwai@suse.de>
