3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Johan Hovold <jhovold@xxxxxxxxx> commit e670c6af12517d08a403487b1122eecf506021cf upstream. Make sure waiting processes are woken on modem-status changes. Currently processes are only woken on termios changes regardless of whether the modem status has changed.
