+Subject: [PATCH] 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.
