this patch is causing a regression on the Clevo NL50RU of which the touchpad
instantly wakes up the device when going to sleep. That wasn't triggered until
this patch by the default settings: Setting wake capable but not enabling it by
default. So unless a user enabled it by hand, the device went correctly to sleep.
I'm not deep into this subsystem so I don't know what the best approach is to
?work around this firmware bug?/?fix this issue?:
- Changing the default back again?
- Adding a quirk list for bad devices?
- Maybe this isn't a firmware bug, but the touchpad was not meant to wakeup the
device and we can somehow detect that?
For reference: The debugging issue that lead me here:
https://gitlab.freedesktop.org/drm/amd/-/issues/1722#note_1719789
Kind regards,
Werner
