   4 Subject: [PATCH 236/806] staging: bcm2835-camera: Add hint about possible
   5  faulty GPU mem config
   6
   7 As per default the GPU memory config of the Raspberry Pi isn't sufficient
   8 for the camera usage. Even worse the bcm2835 camera doesn't provide a
   9 helpful error message in this case. So let's add a hint to point the user
  10 to the likely cause.
