The patch looks reasonably, but the description seem misleading.
I believe the real reason why it's ok to use __raw_writew for the
FIFO is that a FIFO by definition is using CPU endian access for
copying byte streams from memory, which is unlike any other MMIO
register that requires fixed-endian accessors.
