Hi Rafael,

Synaptics RMI4 SMBus touchpad on ThinkPad X1 Carbon (5th generation)
fails to suspend when running 5.11-rc kernels: bisected to 
5b6164d3465f ("driver core: Reorder devices on successful probe"),
and reverting that fixes it.  dmesg.xz attached, but go ahead and ask
me to switch on a debug option to extract further info if that may help.

Thanks,
Hugh
