Subject: ALSA: hda - Judge playback stream from stream id in azx_via_get_position()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b4a655e81d4d1d12abc92d29dfb7550e66a08799;p=deliverable%2Flinux.git

ALSA: hda - Judge playback stream from stream id in azx_via_get_position()

Instead of checking the azx_dev index with a fixed number (4), check
the stream direction of the assigned substream.
