Merge tag 'char-misc-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc updates from Greg KH:
 "Here is the big set of char/misc driver patches for 4.17-rc1.

  There are a lot of little things in here, nothing huge, but all
  important to the different hardware types involved:

   -  thunderbolt driver updates

   -  parport updates (people still care...)

   -  nvmem driver updates

   -  mei updates (as always)

   -  hwtracing driver updates

   -  hyperv driver updates

   -  extcon driver updates

   -  ... and a handful of even smaller driver subsystem and individual
      driver updates

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

+Description:	Holds a comma separated list of device unique_ids that
+		are allowed to be connected automatically during system
+		startup (e.g boot devices). The list always contains
+		maximum supported number of unique_ids where unused
+		entries are empty. This allows the userspace software
+		to determine how many entries the controller supports.
+		If there are multiple controllers, each controller has
+		its own ACL list and size may be different between the
+		controllers.
+
+		System BIOS may have an option "Preboot ACL" or similar
+		that needs to be selected before this list is taken into
+		consideration.
+
+		Software always updates a full list in each write.
+
+		If a device is authorized automatically during boot its
+		boot attribute is set to 1.
