From d3116756a710e3cd51293a9d58b525957ab7e784 Mon Sep 17 00:00:00 2001 From: Christian König Date: Mon, 12 Apr 2021 15:11:47 +0200 Subject: drm/ttm: rename bo->mem and make it a pointer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When we want to decouble resource management from buffer management we need to be able to handle resources separately. Add a resource pointer and rename bo->mem so that all code needs to change to access the pointer instead. No functional change.
