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().

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).

This removes the ugly code that was copied from the keyspan driver and
allocates the in urbs in a much shorter code path that can be understood
easier.
Also turned off the interrupt urb when no port was open as it's not nice
to keep the bus busy for no good reason at all (this should be a power
savings.)
All in all, this saved over 40 lines of code and cleaned things up
better.

You can't rely on the fact that the status really is correct like it was.
Also simplified the write path and now we allocate the urb and data on
the fly, instead of trying to do that really odd timeout check which I
am guessing doesn't really work properly. This should speed up the
device by keeping the hardware queue full easier.
As a benefit, this reduces the size of the driver.

This done in anticipation of removal of urb->status, which will make
that patch easier to review and apply in the future.

I think there is a race between usb_serial_put() and
usb_serial_get_by_index() (and get_free_serial()) with regards
to handling the serial port refcount.
usb_serial_get_by_index() gets a reference on the serial port under
table_lock while return_serial releases all the returned ports
from the table under the same lock. However, the table_lock is not
taken around the call to kref_put, theoretically allowing to sneak
in and grab a reference after kref_put has already determined that
the reference count is zero (and before calling destroy_serial)
causing use after free.

Okay, from this it looks like there's a problem in the option.c serial
driver. Glancing at the code, it's obvious why: The thing totally
abuses the USB API.
Try applying this patch; it should help.

Some further cleanup after Oliver's patch to update the tty
buffering. The input buffer is not used at all anymore, so
I removed it.

this is an update of the whiteheat driver. It fixes:
- switch from spinlocks to mutexes to prevent sleeping with a spinlock held
- locking to stop races with disconnect
- error handling for commands that time out

in order to be able to switch back to 'flow-control none'
after having activated 'flow-control rts/cts', I made
a small change to 'pl2303.c'.

this fixes the flushing trouble due to its own buffering for this driver.

the new tty buffering code allows usb drivers to stop private buffering.
In fact we must do so to allow flushing to work correctly. This does so
for the visor driver.
