ALSA: hda - mask buggy stream DMA0 for Broadwell display controller Broadwell display controller has 3 stream DMA engines. DMA0 cannot update DMA postion buffer properly while DMA1 and DMA2 can work well. So this patch masks the buggy DMA0 by keeping it as opened. This is a tentative workaround, so keep the change small as Takashi suggested. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
