ALSA: hda - Support rereading widgets under the function group
A codec may allow software to hide some unused pin/cvt widgets. Sometimes BIOS does not enable the hidden widgets properly although they are needed for the board. Thus the driver need to enable them as a board-specific fixup and the whole tree will change. This patch implements a common code for rereading codec widgets. So the fixup code can call it after enabling the hidden widgets. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
