Thank you for the quick fix!

@eadler: I believe I adressed all your concerns.
Replace tc_prepare() by two callbacks dedicated to locking

Since this commit, I hit a panic during boot.

I continued to use the initial patch for a few days and got several similar panics (5 in total). The three panic strings I encountered are:
- panic: mutex Giant owned at /mnt/home/dumbbell/Projects/freebsd/src/GIT/sys/kern/kern_event.c:2288
- panic: sleepq_add: td 0xfffff8001875d560 to sleep on wchan 0xffffffff836e0fc0 with sleeping prohibited
- panic: page fault

About my setup: I'm using an USB keyboard on a laptop, so all atkbd/ukbd/kbdmux are attached. I'm using ukbd directly (using libinput) for the X session (99% of the time on this laptop) and I believe kbdmux is the one used by the console. I never had a panic with the unpatched evdev.
I didn't try to reproduce the deadlock yet. However, I got two panics:
- First one was: panic: mutex Giant owned at /mnt/home/dumbbell/Projects/freebsd/src/SVN/head/sys/kern/kern_event.c:2288 (while I was away and the laptop had an active X session).
- Second one was: panic: page fault (during boot).

I'm trying this patch right now. Do you have any advice to reproduce the deadlock when the patch is not applied?

Bump libevdev PORTREVISION
Jan 23 2018
Quick question: devel/libevdev needs to be recompiled. Do I need to bump libevdev's PORTREVISION or is it detected automatically?
Add a description to the patch

Yes, that's fine, the patch is small enough. Thank you!

FWIW, the problem doesn't occur with a USB keyboard of the same type.
