MLK-11911-1 mxc IPUv3: capture: Define div_ratio as type of int32_t
The local variable div_ratio could be less than zero, so let's define it as type of int32_t instead of uint32_t. This issue is reported by Coverity: Unsigned compared against 0 (NO_EFFECT) unsigned_compare: This less-than-zero comparison of an unsigned value is never true. div_ratio < 0U. if (div_ratio > 0xFF || div_ratio < 0) { dev_dbg(ipu->dev, "value of pixel_clk extends normal range\n"); return -EINVAL; } Signed-off-by: Liu Ying <Ying.Liu@freescale.com>pull/10/head
