Subject: ALSA: hda - Force buffer alignment for Haswell HDMI controllers
From: Takashi Iwai <[email protected]>
commit 33499a15c2f7addc81695778753c2338b960eff7 upstream.
Haswell HDMI audio controllers seem to get stuck when unaligned buffer
size is used. Let's enable the buffer alignment for the corresponding
entries.
Since AZX_DCAPS_INTEL_PCH contains AZX_DCAPS_BUFSIZE that disables the
buffer alignment forcibly, define AZX_DCAPS_INTEL_HASWELL and put the
necessary AZX_DCAPS bits there.
