From a82f991122b199bcdaf51eb93dcdcd81825de2bf Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Sat, 29 Dec 2018 21:43:11 -0600 Subject: google/buddy: fix Windows ACPI error with WLAN Buddy's WLAN ACPI code was equivalent to, but formatted differently from the other auron variants. Since only differnce is root port used, have buddy use common WLAN ACPI and use preprocessor guards to set the root port correctly. Test: build/boot Buddy, verify Windows 10 boots without ACPI BIOS ERROR.
