From: Ben Skeggs Date: Fri, 4 Sep 2015 04:40:32 +0000 (+1000) Subject: drm/nouveau: remove unnecessary usage of object handles X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcf3f91c34105c3551741febbfc1066aaa7f1db7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/nouveau: remove unnecessary usage of object handles No longer required in a lot of cases, as objects are identified over NVIF via an alternate mechanism since the rework.
