Subject: [PATCH 174/222] bcm2835: camera: check for scene not being found
|
|
|
|
static analysis by cppcheck detected some potential NULL pointer
|
|
dereference issues:
|
|
|
|
[drivers/media/platform/bcm2835/controls.c:854]: (error) Possible null
|
|
pointer dereference: scene
|
|
(and lines 858, 859 too)
|
|
|
|
it is possible that scene is not found because of an invalue ctrl->val
|
|
and is therefore NULL and hence causing a null pointer dereference.
