Aaahh. My fault then. The suspend/resume issue is cause by commit
38ba34a43dbc ("Input: cros_ec_keyb - mark cros_ec_keyb driver as wake
enabled device."), which has been merged to v4.18-rc1.

It looks that I've downloaded wrong patch from the patchwork to reply it
with a a bug report. :( I'm really sorry for the noise in the wrong thread.

Ravi: please let me know how can I help you to debug this issue.
