Merge tag 'driver-core-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here is the set of "big" driver core patches for 4.16-rc1.

  The majority of the work here is in the firmware subsystem, with
  reworks to try to attempt to make the code easier to handle in the
  long run, but no functional change. There's also some tree-wide sysfs
  attribute fixups with lots of acks from the various subsystem
  maintainers, as well as a handful of other normal fixes and changes.

  And finally, some license cleanups for the driver core and sysfs code.

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

What: /sys/devices/.../coredump
Date: December 2017
Contact: Arend van Spriel <aspriel@gmail.com>
Description:
The /sys/devices/.../coredump attribute is only present when the
device is bound to a driver, which provides the .coredump()
callback. The attribute is write only. Anything written to this
file will trigger the .coredump() callback.
Available when CONFIG_DEV_COREDUMP is enabled.

This should not be confused with CONFIG_FIRMWARE_IN_KERNEL, this is for drivers
which enables firmware to be built as part of the kernel build process. This
option, CONFIG_FIRMWARE_IN_KERNEL, will build all firmware for all drivers
enabled which ship its firmware inside the Linux kernel source tree.
There are a few reasons why you might want to consider building your firmware
into the kernel with CONFIG_EXTRA_FIRMWARE though:
