git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull lockdep fix from Thomas Gleixner: "A RT fix for lockdep. lockdep invokes prandom_u32() to create cookies. This worked until prandom_u32() was switched to the real random generator, which takes a spinlock for extraction, which does not work on RT when invoked from atomic contexts. lockdep has no requirement for real random numbers and it turns out sched_clock() is good enough to create the cookie. That works everywhere and is faster" * tag 'locking-urgent-2022-06-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/lockdep: Use sched_clock() for random numbers

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.
