[PATCH] Fix tty drivers which dont set tty_driver->devfs_name

From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>

The following patches fixes tty drivers which dont set devfs_name. Not
doing so will cause the tty layer to create "/dev/<NULL>x" entries when
devfs is being used.

I used "drivername/" in isicom and pcxe because the letter used to
identify them are already used by other drivers.
