I've written a new script called strip_whitespace.pl (included).

One bug is that, if you split or unsplit a string literal that
confuses it.  Otherwise it seems to work.

strip_whitespace.pl drivers/staging/winbond/reg.c > before
apply patch
strip_whitespace.pl drivers/staging/winbond/reg.c > after

`diff before after`.  If they are the same then resend the patch.

regards,
