Re: [PATCH 2/2] HID: i2c-hid: Do not bind to CHPN0001 touchscreen

So thinking more about this it might be cleaner to add a blacklist
of _CID / _HID ACPI-ids for which power-management should be disabled
to drivers/acpi/device_pm.c : acpi_bus_init_power().

When I've some time to look into this I will write a patch following
that approach.

So lets forget about the approach to add an i2c_driver match callback
for now.

Thanks for the update! That sounds better to me from the high level view
that I have. Thanks to you and Dmitry for discussing the details
throughly. Very much appreciated!
