Merge tag 'char-misc-5.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are some small char and misc driver fixes for 5.2-rc4 to resolve
  a number of reported issues.

  The most "notable" one here is the kernel headers in proc^Wsysfs
  fixes. Those changes move the header file info into sysfs and fixes
  the build issues that you reported.

  Other than that, a bunch of small habanalabs driver fixes, some fpga
  driver fixes, and a few other tiny driver fixes.

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