These are not the only such messages. Some driver reject all attempts at
clearing keys in some states and get something similar displayed.

Maybe not with WEXT.. If someone is worried about those messages showing
up, commenting them out is likely the easiest mechanism to avoid that.
It just makes it much more difficult for me to debug issues if I do not
know what exactly has been removed. In many cases, I've been changing
perror() to wpa_printf(MSG_DEBUG, ..., strerror(errno)) which at least
hides the messages by default, but still, users can see them if they
enable debugging. Difficult to say whether that helps that much, but at
least it may be easier to convince that debug output can include "scary
looking messages".
