Hi Greg,

I'm very sorry for that, I swear I compiled it, but clearly I'm missing something
here.

My patch compiles with a warning, but tag v3.15 (tag where my branch is based) does
not issue this warning:

drivers/staging/rtl8192u/ieee80211/ieee80211_crypt.c:203:19: warning:
‘ieee80211_crypto_init’ defined but not used [-Wunused-function]
 static int __init ieee80211_crypto_init(void)
                   ^

I thought that __init functions could be static, is there any problem with that? Care
to shed some light here?

Thank you very much
