From 2c55b16bf0e1492ba662d884c81d324538cafce1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Thu, 27 Apr 2017 17:13:39 +0200 Subject: drm/amdgpu: remove unused and mostly unimplemented CGS functions v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Those functions are all unused and some not even implemented. v2: keep cgs_get_pci_resource, it is used by the ACP driver.
