Subject: [PATCH] [media] s5c73m3: Fix off-by-one valid range checking for fie->index
Date: Tue, 30 Apr 2013 12:42:16 +0800 [thread overview]
Message-ID: <1367296936.5772.2.camel@phoenix> (raw)
Current code uses fie->index as array subscript, thus the valid value range
is 0 ... ARRAY_SIZE(s5c73m3_intervals) - 1.
