0d46c0079a USB: Remove pointless conditional in drivers/usb/serial/io_ti.c::edge_shutdown()
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).

e94fa28f13 USB: mos7720, mos7840: remove redundant urb check
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.

Fix an oops that happens in relation with applying work arounds for buggy
ftdi_sio devices.  The quirks were handled too early because due to changes in
the initialisation of usb serial devices the device was not fully initialised
when the old hook was called.

a6ea438b6d USB: serial: ir_usb: Clean up the worst of it, remove exciting 'crash on open' feature
- Drivers don't call ldisc termios methods. They certainly don't call
them the way this one does - remove wrong call
- The tty buffer code isn't designed to be abused from IRQ handlers and
the new buffering removes the need for the uglies involved - fix them
- Style
- Remove incorrect baud and change handling for termios changes

The driver now has some style, but not a lot - it goes insane if you have
two dongles for example as it continues to use global variables for per
dongle state. That bit isn't my problem.

Remove pointless and wrong 'no change' check

Could do with some good testing as well but again better than adding &&

(The use of BELKIN_SA_BAUD() might seem a bit odd but x/a = b and x/b =
a (rounded for integers)).

568c24adea USB: serial: ark3116.c: Mixed fixups
o	Don't parse the cflag for baud rates, its not valid to do so
	any more and this driver got it wrong anyway
o	Don't do clever termios change checks in drivers and get them
	wrong (arguably we should do some smart ones in the tty core but
	stty to change nothing is *not* a common or critical path

I don't have the hardware so if you can test this carefully please do. I
thought fixing it up this far was better than marking it and other bits of

9e85c5f632 USB: sierra: cleanup the startup and shutdown path
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.

17c2327419 USB: sierra: remove incorrect usage of the urb status field
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.

52f6b5e1f1 synchronization in usb_serial_put
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.
