Subject: [PATCH] ARM: dts: bcm2835_audio missing firmware reference
|
|
|
|
The firmware driver has been changed to count its clients. An earlier
|
|
commit removed the downstream patch permitting the hacky technique of
|
|
passing NULL to rpi_firmware_get to pick up the last instace, but
|
|
failed to add the necessary "firmware" property to the bcm2835_audio
|
|
node. Correct that omission.
