In general huge patches like this are not encouraged and it is better to
split them. At least the printk changes can be in a separate patch. Then
re-naming host to info probably could be another patch. Could you please
rather do a series of smaller patches? Also, if you use dev_info and the
like functions, you probably do not need the pxa3xx_nand prefix anymore.
