Merge tag 'safesetid-bugfix-5.4' of git://github.com/micah-morton/linux 

Pull SafeSetID fix from Micah Morton:
 "Jann Horn sent some patches to fix some bugs in SafeSetID for 5.3.
  After he had done his testing there were a couple small code tweaks
  that went in and caused this bug.

  From what I can see SafeSetID is broken in 5.3 and crashes the kernel
  every time during initialization if you try to use it. I came across
  this bug when backporting Jann's changes for 5.3 to older kernels
  (4.14 and 4.19). I've tested on a Chrome OS device with those kernels
  and verified that this change fixes things.

  It doesn't seem super useful to have this bake in linux-next, since it
  is completely broken in 5.3 and nobody noticed"
