[PATCH] staging: winbond: wb35reg.c Coding style fixes.

From: Lars Lindley
Date: Mon Mar 22 2010 - 17:51:26 EST

I fixed the problems reported by checkpatch.pl excetp for
long lines, a couple of printks and some warnings about usb_free_urb(NULL).
I checked for regressions with Dan Carpenters strip_whitespace.pl
and diff and everything looks good.
Generated .o is identical to master.
