Better not obfuscate the code like that then ;-)

Really, passing the entire register name into an inline function is much
preferred over string concatenation, because it lets you grep for where
certain definitions are used. You can also convert them to ALL_CAPS
identifiers instead of cAmeLCAsE.

Finally, don't use the __raw_readb() style functions but instead use
the regular readb() style, which is the correct one to use in device
drivers.
