-Subject: [PATCH] Rename HDMI ALSA device names, check for enable state
-
-HDMI Alsa devices renamed to match names used by DRM, to
-HDMI 1 and HDMI 2
-
-Check for which HDMI devices are connected and only create
-devices for those that are present.
-
-The rename of the devices might cause some backwards compatibility
-issues, but since this particular part of the driver needs to be
-specifically enabled, I suspect the number of people who will see
-the problem will be very small.
