[ Test Case ]
Boot Ubuntu MATE *or* Ubuntu Desktop with fkms enabled (instead of
kms).
$ cat $ cat /proc/asound/cards
0 [Headphones ]: bcm2835_headpho - bcm2835 Headphones
bcm2835 Headphones
Correct output should be:
$ cat /proc/asound/cards
0 [b1 ]: bcm2835_hdmi - bcm2835 HDMI 1
bcm2835 HDMI 1
1 [Headphones ]: bcm2835_headpho - bcm2835 Headphones
bcm2835 Headphones
[ Fix ]
Cherry pick missing commit ("ARM: dts: bcm2835_audio missing firmware
reference") from raspberrypi linux.
[ Where Problems Could Occur ]
It's a change to the audio portion of the bcm270x DTB so problems will
likely be audio related, like no output device at all.
