Hi,

I have installed the latest 5.10 kernel on Lenovo L13 laptop and
both touchpad and trackpoint work fine. But after resuming from
hibernation mode trackpoint(and 3 buttons) stop working. The kernel
log says:
     elan_i2c 14-0015: failed to read report data: -71

I assume this is because some initial trackpoint setup is done on the
first boot. Then after hibernation the device resets. And the wake-up
code doesn't set it up properly.

Any help would be appreciated.
