[PATCH AUTOSEL 4.19 03/49] Staging: vc04_services: Fix a couple error codes

From: Sasha Levin
Date: Sat Jun 08 2019 - 07:47:09 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit ca4e4efbefbbdde0a7bb3023ea08d491f4daf9b9 ]

These are accidentally returning positive EINVAL instead of negative
-EINVAL. Some of the callers treat positive values as success.

Fixes: 7b3ad5abf027 ("staging: Import the BCM2835 MMAL-based V4L2 camera driver.")
