[PATCH] [media] mb86a20s: remove redundant check if val is less than zero

From: Colin King
Date: Tue Jul 12 2016 - 05:31:31 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The result of mb86a20s_readreg(state, 0x0a) & 0xf is always in the range
0x00 to 0x0f and can never be negative, so remove the redundant check
of the result being less than zero.
