[alsa-devel] [PATCH] HDA-Intel: present all 4 HDMI outputs instead of just the first one

[Anssi Hannula]

Commit 92608badc519a8c1f65d93743396517aaa582b53 in linux kernel added
the possibility of 3 additional HDMI devices on indexes 7-9.

Present all those additional devices using the "hdmi" alias as well.

Note that the hints for these devices do not appear properly and the
devices therefore do not appear in the output of "aplay -L" until the
issue described in "Device name hints and the value of DEV" thread is
fixed (with the exception of DEV=3 which happens to match the device
index of the first hdmi device and is therefore shown).

Also, I don't know what the "hint.device 3" was doing there and
therefore I couldn't test if it continues to work as intended after
changing it to "hint.device $DEVICE". Please check that it is correct.
