Re: [Xen-devel] [PATCH] tools/console: reset tty when xenconsole fails

This routinely happens in Xen 4.4 RC5 with pygrub because something
writes the value "" to the tty xenstore key when using xenconsole.
The cause of this is not yet known, but after this patch it just
results in a harmless error message.

I'm pretty sure this has been here for quite a while -- possibly since 4.3. I've been working around it for some time, at any rate. :-) So I think at this point we should save this for 4.4.1.
