checkpatch.pl output:
	total: 4870 errors, 4611 warnings, 10004 lines checked

You have almost one error/warning per line of code you added.  That
means you will end up replacing all of the driver by the time you are
done.

Are you really going to do that?  It's fine with me, but I better start
get cleanup patches from you and others real soon, or I will drop this
driver from the tree.
