Summary: Goodix touchscreen works intermittently, fails reading config info.
 https://bugzilla.kernel.org/show_bug.cgi?id=156511

Description:  Chuwi Hi12 tablet with Intel cherry-trail Atom Z8300,
the touchscreen does work after bootup most of the time, but sometimes
it does not work without running modprobe.  When it fails the dmesg
log shows the error "Invalid config, using defaults" and when it works
this error is not present.
