# Merge: 08b5fa8 3d27c4d
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Aug 19 09:30:44 2018 -0700
# 
#     Merge tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
#     
#     Pull UIO fix from Greg KH:
#      "Here is a single UIO fix that I forgot to send before 4.18-final came
#       out. It reverts a UIO patch that went in the 4.18 development window
#       that was causing problems.
#     
#       This patch has been in linux-next for a while with no problems, I just
#       forgot to send it earlier, or as part of the larger char/misc patch
#       series from yesterday, my fault"
#     
#     * tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
#       Revert "uio: use request_threaded_irq instead"
