USB: cdc-acm: check for valid interfaces

We need to check that we have both a valid data and control inteface for both
types of headers (union and not union.)

2014-11-25T01:21:41+00:00

If probe() fails not only the attributes need to be removed
but also the memory freed.

USB: cdc-acm: add quirk for control-line state requests

2014-11-06T20:25:40+00:00

Add new quirk for devices that cannot handle control-line state
requests.

Note that we currently send these requests to all devices, regardless of
whether they claim to support it, but that errors are only logged if
support is claimed.

Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which
only changed the timings for these requests slightly, this has been
reported to cause occasional firmware crashes on Simtec Electronics
Entropy Key devices after re-enumeration. Enable the quirk for this
device.

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

2014-11-05T19:25:25+00:00

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.

cdc-acm: Drop the warning for unusual capabilities

Let's drop the warning for modems with unusual capabilities,
the associated quirk and blacklist. They made little sense.

cdc-acm: ensure that termios get set when the port is activated

2014-11-03T23:26:15+00:00

The driver wasn't properly configuring the hardware for the current
termios settings under all conditions.  Ensure that termios are
written to the device when the port is activated.
