USB: cdc-acm: check for valid interfaces

2015-01-16T14:59:32+00:00

commit 403dff4e2c94f275e24fd85f40b2732ffec268a1 upstream.

USB: cdc-acm: only raise DTR on transitions from B0

2014-11-14T17:00:03+00:00

commit 4473d054ceb572557954f9536731d39b20937b0c upstream.

Make sure to only raise DTR on transitions from B0 in set_termios.

Also allow set_termios to be called from open with a termios_old of
NULL. Note that DTR will not be raised prematurely in this case.

USB: cdc-acm: fix runtime PM imbalance at shutdown

2014-06-26T19:15:41+00:00

commit 5292afa657d0e790b7479ad8eef9450c1e040b3d upstream.

Make sure only to decrement the PM counters if they were actually
incremented.

Note that the USB PM counter, but not necessarily the driver core PM
counter, is reset when the interface is unbound.

USB: cdc-acm: fix I/O after failed open

2014-06-26T19:15:41+00:00

commit e4c36076c2a6195ec62c35b03c3fde84d0087dc8 upstream.

Make sure to kill any already submitted read urbs on read-urb submission
failures in open in order to prevent doing I/O for a closed port.

USB: cdc-acm: fix potential urb leak and PM imbalance in write

commit 183a45087d126d126e8dd1d9b2602fc129dff9ad upstream.

Make sure to check return value of autopm get in write() in order to
avoid urb leak and PM counter imbalance on errors.

USB: cdc-acm: fix shutdown and suspend race

2014-06-26T19:15:41+00:00

commit ed797074031a37bb9bf4a70952fffc606b77274d upstream.

We should stop I/O unconditionally at suspend rather than rely on the
tty-port initialised flag (which is set prior to stopping I/O during
shutdown) in order to prevent suspend returning with URBs still active.
