This patch (as997) fixes a bug in the USB serial core. The core needs
to pay attention to drivers' requirements regarding the number and
type of endpoints a device has.
At the same time, the patch changes the NUM_DONT_CARE constant (which
is stored in a single-byte field) from -1 to a safer, unsigned value.
It also improves the kerneldoc for several fields in the
usb_serial_driver structure.
Finally, the patch replaces a list_for_each() with list_for_each_entry().

This patch adds an additional device ID to the cp2101 USB serial

documentation) bundled with a built-in CP2102 for serial/USB

the iuu_phoenix driver submits another URB from a completion handler.
This dictates a certain order of calls to usb_kill_urb() in kill_traffic().
As other drivers may do it the other way round, we need to use both
orders in kill_traffic().
This patch does so and should be merged before iuu_phoenix is merged.

Some usb-serial devices (e.g. certain Edgeport models) have more than
one serial port on the same USB device/interface.
Currently the only way to distinguish these ports in userspace is by
their minor device number: the driver makes them consecutive and in
stable order.
However, for the purpose of stable naming with udev this is
insufficient: when udev handles the ADD event for one of the ports it
doesn't know what minor number the other one has.
To make stable naming easier, export the port number via sysfs.

This patch contains two fixes submitted by Ondrej Palkovsky:
- the 'ACK' packet is sent after the transfer of the USB packet is
completed, i.e. in the write_callback function. Because the close
function sends the 'abort' command, a parameter is added that allows
the caller of garmin_write_bulk to specify, if the 'ack' should be
propagated to the serial link or dimissed.
This fixes the problem with gpsbabel, it has sent several packets that
were acknowledged before they were sent to the GPS and GpsBabel closed
the device - thus effectively cancelled all outstanding requests in the
queue.
- removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed
them into counters. It evades USB reset of the gps on every device close.

Coverity scan found (CID: 1708) this in
drivers/usb/serial/io_ti.c::edge_shutdown() :
...
2797 for (i=0; i < serial->num_ports; ++i) {
2798 edge_port = usb_get_serial_port_data(serial->port[i]);
2799 edge_remove_sysfs_attrs(edge_port->port);
2800 if (edge_port) {
2801 edge_buf_free(edge_port->ep_out_buf);
2802 kfree(edge_port);
2803 }
2804 usb_set_serial_port_data(serial->port[i], NULL);
2805 }
...
It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.
This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as
REVERSE_INULLs (NULL check performed after dereference). But looking at
the other drivers I can't see any similar tests and the USB core already
makes sure urb is non-null - so might as well get rid of the checks.
