   4 Subject: [PATCH] ARM: dts: bcm2835_audio missing firmware reference
   5
   6 The firmware driver has been changed to count its clients. An earlier
   7 commit removed the downstream patch permitting the hacky technique of
   8 passing NULL to rpi_firmware_get to pick up the last instace, but
   9 failed to add the necessary "firmware" property to the bcm2835_audio
  10 node. Correct that omission.
