[U-Boot] [PATCH] usbtty: Added additional usbtty_configured() checks to get around hang when usb is not connected but multi-io is set up.

This adds additional checks in usbtty_puts() and usbtty_putc() to get around a hang when usb is not connected but multi-io (setenv stdout serial,usbtty etc) is set up by the user. We hang because the buffers get full because usb isn't connected. --- drivers/serial/usbtty.c |9 - 1 fi
