-Subject: [PATCH] staging: bcm2835: Don't probe if no camera is
- detected
-
-It is a waste of resources to load the camera driver in case there isn't
-a camera actually connected to the Raspberry Pi. This solution also
-avoids a NULL ptr dereference of mmal instance on driver unload.
-
-Fixes: 7b3ad5abf027 ("staging: Import the BCM2835 MMAL-based V4L2 camera driver.")
-Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com>
