This feels painful, we shouldn't have to be faffing about with the lock
like this for basic I/O operations.  It feels like we should be pushing
the lock down into the register access functions - looking at the driver
I can't really see any reason why all this stuff is being done by hand,
especially when we've got explicit read/modify/write bitmask operations.
