From: Paulo Alcantara <pc@xxxxxxxxxxxxx> commit fc99045effa81fdf509c2a97cbb7e6e8f2fd4443 upstream. When mounting a CIFS share with 'guest' mount option, mount.cifs(8) will set empty password= and password2= options. Currently we only handle empty strings from user= and password= options, so the mount will fail with cifs: Bad value for 'password2' Fix this by handling empty string from password2= option as well.
