[PATCH] HID: logitech-dj: add support for the static device in the Powerplay mat/receiver

From: Filipe LaÃns
Date: Wed Jan 15 2020 - 15:19:20 EST


The Logitech G Powerplay has a lightspeed receiver with a static HID++
device with ID 7 attached to it to. It is used to configure the led on
the mat. For this reason I increased the max number of devices.
