[PATCH 3.18 33/92] [media] v4l: s5c73m3: fix negation operator

From: Greg Kroah-Hartman
Date: Wed Aug 09 2017 - 16:55:59 EST


3.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Andrzej Hajda <a.hajda@xxxxxxxxxxx>

commit a2370ba2752538404e363346b339869c9973aeac upstream.

Bool values should be negated using logical operators. Using bitwise operators
results in unexpected and possibly incorrect results.
