[PATCH] SERIAL: Fix oops when removing suspended serial port
[SERIAL] Fix oops when removing suspended serial port
A serial card might have been removed when the system is resumed.
This results in a suspended port being shut down, which results in
the ports shutdown method being called twice in a row. This causes
BUGs. Avoid this by tracking the suspended state separately from
the initialised state.
