From 576f42effe1af94f1bf546b1b91ef85b309d0945 Mon Sep 17 00:00:00 2001 From: Tomohito Esaki Date: Tue, 4 Apr 2017 17:54:24 +0100 Subject: [PATCH] compositor-drm: Refactor destroy drm_fb function The drm_fb destroy callback to mostly the same thing regardless of whether the buffer is a dumb buffer or gbm buffer. This patch refactors the common parts into a new function that can be called for both cases.
