USB: digi_acceleport: remove unused MSR-wait queue
Remove unused, private modem-status wait queue from driver. If TIOCMIWAIT is ever implemented it must not rely on a private wait queue which may have been released when woken up. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
