Pull USB fixes from Greg KH:
 "Here are a bunch (65) of USB fixes for 4.7-rc4.  Sorry about the
  quantity, I've been slow in getting these out.

  The majority are the "normal" gadget, musb, and xhci fixes, that we
  all are used to.  There are also a few other tiny fixes resolving a
  number of reported issues that showed up in 4.7-rc1.

  All of these have been in linux-next"

Pull driver core fixes from Greg KH:
 "Here are a small number of debugfs, ISA, and one driver core fix for
  4.7-rc4.

  All of these resolve reported issues.  The ISA ones have spent the
  least amount of time in linux-next, sorry about that, I didn't realize
  they were regressions that needed to get in now (thanks to Thorsten
  for the prodding!) but they do all pass the 0-day bot tests.  The
  others have been in linux-next for a while now.

  Full details about them are in the shortlog below"

* tag 'driver-core-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
  isa: Dummy isa_register_driver should return error code
  isa: Call isa_bus_init before dependent ISA bus drivers register
  watchdog: ebc-c384_wdt: Allow build for X86_64

  debugfs: open_proxy_open(): avoid double fops release
  debugfs: full_proxy_open(): free proxy on ->open() failure
  kernel/kcov: unproxify debugfs file's fops

The inline isa_register_driver stub simply allows compilation on systems
with CONFIG_ISA disabled; the dummy isa_register_driver does not
register an isa_driver at all. The inline isa_register_driver should
return -ENODEV to indicate lack of support when attempting to register
an isa_driver on such a system with CONFIG_ISA disabled.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.

To allow ISA-style drivers on modern systems, this patch introduces the
ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now
build conditionally on the ISA_BUS_API Kconfig option, which defaults to
the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the
ISA_BUS_API Kconfig option to be selected on architectures which do not
enable ISA (e.g. X86_64).

The ISA_BUS Kconfig option is currently only implemented for X86
architectures. Other architectures may have their own ISA_BUS Kconfig
options added as required.

  probably hard to reproduce before client changes in 3.20 allowed the
  client to perform parallel opens).

  Also fix a 4.1 backchannel crash due to rpc multipath changes in 4.6.

Pull overlayfs fixes from Miklos Szeredi:
 "This contains two regression fixes: one for the xattr API update and
  one for using the mounter's creds in file creation in overlayfs.

  There's also a fix for a bug in handling hard linked AF_UNIX sockets
  that's been there from day one.  This fix is overlayfs only despite
  the fact that it touches code outside the overlay filesystem: d_real()
  is an identity function for all except overlay dentries"

* 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
  ovl: fix uid/gid when creating over whiteout
  ovl: xattr filter fix
  af_unix: fix hard linked sockets on overlay
  vfs: add d_real_inode() helper

The spec allows backchannels for multiple clients to share the same tcp
connection.  When that happens, we need to use the same xprt for all of
them.  Similarly, we need the same xps.

This fixes list corruption introduced by the multipath code.
