Hi, Hans
Thanks for the review. And sorry for I'm not really familiar with
mailing list, so didn't reply early.
Actually the reason why I submit this patch, is the vendor ask we do
this, they do not want enable touchpad wakeup.
And yes, this device use hid-multitouch.
Right, I already suspected that. I guess they might be seeing
a similar issue as what I am seeing on the Asus T101HA.
Here when closed the lid comes to close to the touchpad and
it starts sending spurious events, resulting in immediate
wakeup from suspend.
I have a workaround patch for that issue here:
https://github.com/jwrdegoede/linux-sunxi/commit/cb3a4c23b94bc3646953d00cea183d4e8fddeea0
As the commit message explains that patch is not yet
ready for upstream. It should probably be modified to
only disable the touchpad this way when remote-wakeup is
disabled (at which point it mainly becomes a power-saving
feature).
So if the BYD zhaoxin notebook has the same issue, then
adding a quirk to disable remote-wakeup is likely still the
right thing to do. But first I would like to understand the
problem better.

Hans

You are still not explaining why this is necessary ?
And you did not answer my question if this touchpad is using hid-multitouch
either ?
So NACK (rejection) from me until both questions are answered. The commi
message for a quirk should always explain why a quirk is necessary and
"we would like to disable touchpad wakeup on this notebook by default"
does not explain why you want to do that.
