a3fbedf98f usb: patches for v4.3 merge window
New support for Allwinne SoC on the MUSB driver has been added to the list of
 glue layers. MUSB also got support for building all DMA engines in one binary;
 this will be great for distros.
 
 DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
 tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
 maxpacket size transfers are > 512 bytes.
 
 Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
 now required to set these flags up when adding endpoints to the framework.
 
 Other than these, we have the usual set of miscelaneous cleanups and minor
 fixes.

d6d22922d9 usb: gadget: rndis: remove the limit of available rndis connections
RNDIS function has a limitation on the number of allowed instances.
So far it has been RNDIS_MAX_CONFIGS, which happens to be one.
In order to eliminate this kind of arbitrary limitation we should not
preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params
instances but instead allow allocating them on demand.

This patch allocates struct rndis_params on demand in rndis_register().
Coversly, the structure is free()'d in rndis_deregister().
If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which
is the same behaviour as before, but the moment of creation is delayed
until struct rndis_params is actually allocated.

rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

e3aa205aa1 Documentation usb serial: fixed how to provide vendor and product id
While trying to test a Cinterion GSM/GPS/3G module I had reconfigured
the USB interface by mistake and therefore needed to run a different
USB driver than CDC-ACM. It turned out that I need the "usbserial" driver.

This file is an official description how to use it:
Documentation/usb/usb-serial.txt

But it is outdated. The parameters vendor= and product= have been
superseded by a /sys interface.

Here was the solution:

https://bbs.archlinux.org/viewtopic.php?id=175499

  insmod usbserial vendor=0x#### product=0x####

becomes (first #### is vendor, second is product)

  modprobe usbserial
  echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id

This patch changes the documentation file to describe the modern variant.
Please note that the old one still works (if compiled as module).

ceb6c9c862 USB / PM: Drop CONFIG_PM_RUNTIME from the USB core
After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so quite a few
depend on CONFIG_PM (or even dropped in some cases).

Replace CONFIG_PM_RUNTIME with CONFIG_PM in the USB core code
and documentation.

37ebb54915 usb: hub: rename khubd to hub_wq in documentation and comments
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

005799d560 uwb: doc: bring uwb documentation up to date
The existing UWB documentation states that UWB devices show up in
/sys/class/uwb and /sys/bus/uwb/devices.  Up until the most recent
changes to add uwb devices to their own bus, neither of these statements
were actually true.  Now, UWB devices do show up in /sys/bus/uwb/devices
so the documentation has been updated to reflect that and removed
references to /sys/class/uwb.

The existing documentation also states that local UWB radio controller
(RC) devices also show up as UWB devices along with their wireless peer
UWB devices under /sys/class/uwb.  This is not true so that statement
has been removed.
