[alsa-devel] [PATCH 2/2] ALSA: hda - Drop AZX_DCAPS_ALIGN_BUFSIZE

[Raymond Yau]

>
> We introduced AZX_DCAPS_ALIGN_BUFSIZE to explicity show that the
> controller needs the alignment, with a slight hope that the buffer
> size alignment will be disabled as default in future.  But the reality
> tells that most chips need the buffer size alignment, and it'll be
> likely enabled in future, too.
>
> This patch drops AZX_DCAPS_ALIGN_BUFSIZE to give back one more
> previous DCAPS bit for future use.  At the same time, rename
> AZX_DCAPS_BUFSIZE with AZX_DCAPS_NO_ALIGN_BUFSIZE for avoiding
> confusion.
>
> AZX_DCAPS_ALIGN_BUFSIZE are still kept (but commented out) in each
> DCAPS presets for a purpose as markers.

Does it mean that there are still a few  hda controllers support arbitrary
period size or no hda controller support arbitrary period size ?
