Subject: USB: mos7840: fix broken TIOCMIWAIT
From: Johan Hovold <[email protected]>
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.
