[PATCH] console: handle input consoles in of_console_by_stdout_path() gracefully

[Bastian Krause]

With CONFIG_INPUT=y, inputs are registered as consoles without setting
the dev member. This leads to a NULL pointer dereference when passed to
dev_of_node().

So add a check prior to calling dev_of_node() with a NULL pointer to
prevent this.
