2010-09-29Staging: west bridge, removal of " " before ";"David Cross
This patch fixes removes all of the the " ;"'s in the west bridge driver and instead replaces them with ";" only. Although this is a large patch, this is the only thing that it does. I can break it up on a file basis if needed. Signed-off-by: David Cross <david.cross@cypress.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
