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"
