[PATCH] se401: fix "&& 0x" typo

[PATCH] se401: fix "&& 0x" typo

[Alexey Dobriyan]

Code there survived trivial regexp made earlier, but after bulk preprocessing
was done...

===>	if (!cp[2] && 0x40) {	<===
		printk("<3>" "%s: " "Bayer format not supported!" ...
		return 1;
	}


NOTE: to me, check or error message should be reverted, but I know nothing
about this driver.

Your patch looks to be coherent. However, I suspect that this will break
the driver. There are some functions at the driver for decoding Bayer
format. Without your patch, the if condition will never occur. So, Bayer
decoding will work. 

IMO, the better is to add an #if 0 at the test.
