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.

This patch (as937) fixes a minor bug in the autosuspend usage-counting
code.  Each hub's usage counter keeps track of the number of
unsuspended children.  However the current driver increments the
counter after registering a new child, by which time the child may
already have been suspended and caused the counter to go negative.
The obvious solution is to increment the counter before registering
the child.

This patch (as934) adds a new readonly binary sysfs attribute file
called "descriptors" for each USB device.  The attribute contains the
device descriptor followed by the raw descriptor entry (config plug
subsidiary descriptors) for the current configuration.

Having this information available in fixed-format binary makes life a
lot easier for user programs by avoiding the need to open, read, and
parse multiple sysfs text files.

The information in this attribute file is much like that in usbfs's
device file, but there are some significant differences:

	The 2-byte fields in the device descriptor are left in
	little-endian byte order, as they appear on the bus and
	in the kernel.

	Only one raw descriptor set is presented, that of the
	current configuration.

	Opening this file will not cause a suspended device to be
	autoresumed.

The last item in particular should be a big selling point for libusb,
which currently forces all USB devices to be resumed as it scans the
device tree.

This patch (as931b), adapted from a patch by Olav Kongas, makes a small
set of conservative changes to the isp116x-hcd driver in preparation
for the removal of urb->status.

	finish_request() is moved up in the source and is called
	as soon as the URB is known to have completed, rather than
	after all the active endpoints have been scanned.

	The status of a completed URB is kept in a local variable
	and copied to urb->status only when the URB is about to be
	given back.

	-EREMOTEIO error status for control transfers is set after
	the status stage rather than when the short packet arrives.

	Some unnecessary uses of urb->lock are removed.

I found the first regresson in the rewritten ("all dynamic" and "no races")
driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB
being submitted successfuly. This causes the application to resubmit the
same data erroneously.

The fix is to pretend that the transfer has succeeded even if URB was
merely queued. It is the same behaviour as with the old version.

Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).

While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():

- This prevents ide-{disk,tape,scsi} device drivers from obtaining
  REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
  these drivers and which are potentially harmful (as reported by Andrew).

- There is no functionality loss since aforementioned ioctls will now be
  handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
  ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
  (for devices using ide-cd driver).
