Hi.

This patch fixes these warnings:
cpia.c:1686: Warnung: comparison is always false due to limited range of data type
cpia.c:1688: Warnung: comparison is always false due to limited range of data type
cpia.c:1690: Warnung: comparison is always false due to limited range of data type
cpia.c:1692: Warnung: comparison is always false due to limited range of data type

The warnings are thrown, because an u8 is tested against >255.
As far as I can see, these tests are completely useless,
because u8 will never be >255.
struct cam_params {
[SNIP]
	struct {
		u8 gainMode;
		u8 expMode;
		u8 compMode;
		u8 centreWeight;
		u8 gain;
		u8 fineExp;
		u8 coarseExpLo;
		u8 coarseExpHi;
		u8 redComp;
		u8 green1Comp;
		u8 green2Comp;
		u8 blueComp;
	} exposure;
[SNIP]
};
