5.17-rc[1-3] on Lenovo ThinkPad X1 Carbon 5th gen: when lid closed
and opened and system resumed, the touchpad cursor cannot be moved.
Some dmesg from bootup:
[ 2.211061] rmi4_smbus 6-002c: registering SMbus-connected sensor

Some dmesg from resume:

Bisection led to 172d931910e1db800f4e71e8ed92281b6f8c6ee2
("i2c: enable async suspend/resume on i2c client devices")
and reverting that fixes it for me.
