Hello,
I think I talked too fast: it seems impossible to have both drivers
(leds-hp-disk and lis3lv02d) working at the same time. Only the first
driver loaded is used.

After a little look at it, I think it comes from the fact that both
drivers are assigned to the same MODALIAS (HPQ0004). The ACPI PNP
(through the generic bus infrastructure) only declare the device to one
of the drivers supporting it, not all of them.

How can I tell to ACPI that it should load both drivers for the same PNP
ID match?

Eric
