Subject: [PATCH 236/782] staging: bcm2835-camera: Add hint about possible
|
|
faulty GPU mem config
|
|
|
|
As per default the GPU memory config of the Raspberry Pi isn't sufficient
|
|
for the camera usage. Even worse the bcm2835 camera doesn't provide a
|
|
helpful error message in this case. So let's add a hint to point the user
|
|
to the likely cause.
