In HDA extended bus the HDA link objects are created when multilink capabilities are parsed. We need a routine which free up these link objects for a bus. So add snd_hdac_link_free_all routine Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
