How have you verified this change is correct?
Have you checked that the callers of this function in
fs/cifs/sess.c do the appropriate things with with a
negative return value?
The return value is now set into a struct member variable
as a positive value,
sess_data->result = rc;
Have you checked all the users of this member variable?
If you have, you should say so in the commit message.
