unneccessary error message within wpa_supplicant/openssl

[Dennis Borgmann]

Hello!

Several times, I observed an error using EAP-TLS with
wpa_supplicant/hostapd in combination with freeradius, that looks like this:

EAP: Initialize selected EAP method: vendor 0 method 13 (TLS)
TLS: using phase1 config options
TLS: Trusted root certificate(s) loaded

SSL: Private key loaded successfully

Anway, everything works quite ok afterwards (as it states, "SSL: Private
key loaded successfully"). Shouldn't this errormessage disappear rather?
This is stated by a ubuntu user as well, I just found this message on
the internet:
https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/597050

So, why complaining about this error, if it essentially is no error? It
just cost me 2 hours, which could have been saved...

Kind regards,
Dennis
