Subject: staging: cpia: fix camera file owner in cpia_open()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c888d4e7b2644c7ff17098b0b521c29b98e0abd0;p=linux-beck.git

staging: cpia: fix camera file owner in cpia_open()

Use effective UID instead of real UID for camera owner.
There is no need to check for pending signals just before successfull
return.  Exit in case of pending signal also leaved camera in open state.
