[PATCH trivial] drivers/usb: Remove unnecessary return;s from void functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
