ALSA: hda - apply SKL display power request/release patch to BXT
For SKL, only the HDMI codec is in the display power well while the HD-A controller isn't. So the codec flag 'link_power_control' is set to request/release the display power via bus link_power ops. For BXT, the power well design is the same as SKL, so the patch should be applied to BXT too. Signed-off-by: Lu, Han <han.lu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
