Merge tag 'char-misc-5.19-rc3-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver fixes for real from Greg KH: "Let's tag the proper branch this time... Here are some small char/misc driver fixes for 5.19-rc3 that resolve some reported issues. They include: - mei driver fixes - comedi driver fix - rtsx build warning fix - fsl-mc-bus driver fix All of these have been in linux-next for a while with no reported issues" This is what the merge in commit f0ec9c65a8d6 _should_ have merged, but Greg fat-fingered the pull request and I got some small changes from linux-next instead there.
