From 96962178475ae8040f40dff3a44beb9f69181421 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 23 Mar 2017 21:17:48 +0200 Subject: leds: lp3952: Remove ACPI support for lp3952 In ACPI world any ID should be carefully chosen and registered officially. The discussion [1] as I read it gets to wilful assignment an ID for non-existing real DSDT example. Rafael already told [2] how this device would be enumerated using compatible string. To be more precise look at the possible DSDT excerpt below: Device (LDX0) { Name (_HID, "PRP0001") Name (_DDN, "TI LP3952 compatible led driver") ... }) Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"compatible", "ti,lp3952"}, ... } }) Based on above, remove non-official ACPI IDs and enumeration from the driver. Note: currently driver has no compatible strings at all, to make above working one should add at least one.
