From a720dee5e039238a44c0142dfccdc0e35c1125f7 Mon Sep 17 00:00:00 2001 From: "Luke D. Jones" Date: Sat, 13 Jul 2024 19:47:33 +1200 Subject: hid-asus: use hid for brightness control on keyboard On almost all ASUS ROG series laptops the MCU used for the USB keyboard also has a HID packet used for setting the brightness. This is usually the same as the WMI method. But in some laptops the WMI method either is missing or doesn't work, so we should default to the HID control. Signed-off-by: Luke D.
