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

[Colin King]

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.
