Very true. There are a *lot* of massively long lines.

This has been a learning experience. I wasn't sure how strict the rules for
submissions were.

There are other things besides line lengths that I want to fix in
rtl8192u. Related to that, I just sent a 3rd version which includes fixes for
these bool comparisons for the rest of the files in drivers/staging/rtl8192u/

Thanks so much for taking the time to review. Appreciated.
