Hey Jamie and Roel

Looking at drivers with:

$ grep -rP --include=*.[ch] "(\b[\w\[\]\>\._\-]+)\s*\!\=\s*[\w\[\]\>\._\-]+\s*\|\|\s*\1\s*\!\=" drivers

drivers/crypto/picoxcell_crypto.c:	if ((len != AES_KEYSIZE_128 || len != AES_KEYSIZE_256) &&
drivers/crypto/picoxcell_crypto.c:	} else if ((len != AES_KEYSIZE_128 || len != AES_KEYSIZE_256) &&

Most likely these should be && not ||.
