Merge tag 'driver-core-4.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core fixes from Greg KH:
 "Here are 3 small fixes for some reported issues:

   - a debugfs build error that lots of people have reported

   - a Kconfig help text cleanup now that the firmware is not in the
     kernel tree

   - an ISA bus bug fix for a reported issue that has been there since
     2.6.18.

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

	  The kernel source tree includes a number of firmware 'blobs'

	  that are used by various drivers. The recommended way to

	  use these is to run "make firmware_install", which, after

	  converting ihex files to binary, copies all of the needed

	  binary files in firmware/ to /lib/firmware/ on your system so

	  that they can be loaded by userspace helpers on request.

	  Various drivers in the kernel source tree may require firmware,

	  which is generally available in your distribution's linux-firmware

	  package.



	  The linux-firmware package should install firmware into

	  /lib/firmware/ on your system, so they can be loaded by userspace

	  helpers on request.



	  Enabling this option will build each required firmware blob

	  into the kernel directly, where request_firmware() will find

	  them without having to call out to userspace. This may be

	  useful if your root file system requires a device that uses

	  such firmware and do not wish to use an initrd.

	  device that uses such firmware and you do not wish to use an

	  initrd.



	  This single option controls the inclusion of firmware for

	  every driver that uses request_firmware() and ships its

	  firmware in the kernel source tree, which avoids a

	  every driver that uses request_firmware(), which avoids a

	  proliferation of 'Include firmware for xxx device' options.



	  Say 'N' and let firmware be loaded from userspace.
