In addition to Greg's comments, I'd ask while here, what about the
misleading lack of indent on the notify_wx_assoc_event() call above?
That would concern me more than trivial equality check changes that
gcc will no doubt optimize to the same thing.

But why leave the "else if" vs an "else"? You know this:

staging/rtl8192u/ieee80211/ieee80211.h: bool is_silent_reset;

and you've already tested "if (!ieee->is_silent_reset)". By
definition, a bool can have only two values and you've already
tested for one of them, so...

Paul.
