This looks bogus to me, it's complaining about a copy_from_user into an __le32 because it can't determine the number of bytes to be copied. That number is a parameter to the function, but the function is static and only called with values of 1, 2 or 4. I've added a test that seems to make the compiler happy, so this will be fixed in tomorrow's tree. Thanks!
