In the future, you can help speed up the review process by helping
the reviewer/maintainer. How? In your commit log. Describe the
end user symptoms and how the problem was found, why it happens
and what is the best fix for the problem (assuming it isn't trivially
obvious). So, instead of just translating the C change into words
for a commit log like you had above, you could have instead had...

When trying to use an RL8192 with auth mode foo and module
parameter blah blah, the driver fails to connect, only showing
blah blah in the logs.

This happens because auth_parse blah blah and returns blah
which is incorrectly interpreted by foo_bar() since it is in
the wrong endian as blah is in native byte order and ...

We fix it by noting the error value should be ... since ...

Also, minor nit ; if you are going to put a path fragment in the subject,
then don't replace all the / with ": " --- i.e. use

[PATCH] staging: rtl8192u/ieee80211/ieee80211_softmac.c: auth parse error code byte order fix

or

[PATCH] staging/rtl8192u: ieee80211_softmac.c - auth parse error code byte order fix
