4 Subject: [PATCH 236/703] 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.
