[Qemu-stable] [PATCH 2/2] chardev: fix "info chardev" output


From: Gerd Hoffmann
Subject: [Qemu-stable] [PATCH 2/2] chardev: fix "info chardev" output
Date: Tue, 28 May 2013 12:27:59 +0200

Fill unset CharDriverState->filename with the backend name, so
'info chardev' will return at least the chardev type.  Don't
touch it in case the chardev init function filled it already,
like the socket+pty chardevs do for example.
