Staging: winbond: wb35rx.c Coding style fixes v2.

New patch that fixes an unclear comment too.

I fixed checkpatch issues except for long lines and printk:s.
I also removed version comments and the () in a return statement.
Generated .o is identical to master and i checked the code with
Dan Carpenters strip_whitespace.pl and diff.
