drivers/usb: Remove unnecessary return's from void functions

Greg prefers this to go through the trivial tree. http://lkml.org/lkml/2010/6/24/1 There are about 2500 void functions in drivers/usb Only a few used return; at end of function. Standardize them a bit. Moved a statement down a line in drivers/usb/host/u132-hcd.c Signed-off-by: Joe Perches <[email protected]> Signed-off-by: Jiri Kosina <[email protected]>
