[ Fix ]

https://github.com/raspberrypi/linux/commit/58f43fcb0348359e7e19860c99e61d2648e33f8d

[ Test Case ]

Boot kernel, no splat.

[ Where Problems Could Occur ]

Fix is isolated to the vc4 driver, so Pi systems that use this driver
might fall over.

  [ Fix ]
  
  
https://github.com/raspberrypi/linux/commit/58f43fcb0348359e7e19860c99e61d2648e33f8d
  
  [ Test Case ]
  
  Boot kernel, no splat.
  
  [ Where Problems Could Occur ]
  
  Fix is isolated to the vc4 driver, so Pi systems that use this driver
  might fall over.
