Pull USB patches from Greg KH:
 "Here's the big pull request for the USB driver tree for 3.20-rc1.

  Nothing major happening here, just lots of gadget driver updates, new
  device ids, and a bunch of cleanups.

  All of these have been in linux-next for a while with no reported
  issues"

usb: use %*pb[l] to print bitmaps including cpumasks and nodemasks

2015-02-14T05:21:38+00:00

printk and friends can now format bitmaps using '%*pb[l]'.  cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

* drivers/uwb/drp.c::uwb_drp_handle_alien_drp() was formatting mas.bm
  into a buffer but never used it.  Removed.

wusb: replace memset by memzero_explicit

2014-12-03T00:15:02+00:00

Memset on a local variable may be removed when it is called just before the
variable goes out of scope.  Using memzero_explicit defeats this
optimization.  A simplified version of the semantic patch that makes this
change is as follows: (http://coccinelle.lip6.fr/)

// 
@@
identifier x;
type T;
@@

{
... when any
T x[...];
... when any
    when exists
- memset
+ memzero_explicit
  (x,
-0,
  ...)
... when != x
    when strict
}
//

usb: hub: rename khubd to hub_wq in documentation and comments

2014-09-24T05:33:19+00:00

USB hub has started to use a workqueue instead of kthread. Let's update
the documentation and comments here and there.

This patch mostly just replaces "khubd" with "hub_wq". There are only few
exceptions where the whole sentence was updated. These more complicated
changes can be found in the following files:

	   Documentation/usb/hotplug.txt
	   drivers/net/usb/usbnet.c
	   drivers/usb/core/hcd.c
	   drivers/usb/host/ohci-hcd.c
	   drivers/usb/host/xhci.c

usb: wusbcore: fix device disconnect on rekey timeout

2014-09-24T05:06:59+00:00

If three or more wireless devices are connected and two of them
disconnect between 1-3 seconds apart, it can cause the HWA to disconnect
the remaining devices due to failing to see a DN_Alive message from
them.  This happens because when the HWA detects that the first device
is gone, it will attempt to rekey the remaining devices.  If one of the
devices is not responding because it has also been disconnected but not
yet timed out, the synchronous rekey operation running on the wusbd
workqueue can block for up to 5 seconds.  This will prevent the
KEEPALIVE timer from running and DN_Alive messages from being processed
because they are processed by the same workqueue.  This patch moves the
rekey operation to a separate workqueue since it is the only wusb work
item that needs to communicate directly with wireless devices.  The rest
of the WUSB work items either perform no device IO or communicate
directly with the host controller and should not be blocked out by a
non-responding wireless device.

usb: wusbcore: skip done segs before completing aborted transfer

2014-09-24T05:06:59+00:00

When completing an aborted transfer, skip done segs before calling
wa_complete_remaining_xfer_segs to avoid a runtime warning.  The warning
is harmless in this case but avoiding it prevents false error reports.
