From c52837238038f61b6511eadee94fcab622d635f0 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 24 Nov 2017 10:43:07 +0100 Subject: [PATCH] drm/etnaviv: simplify submit_create Use kzalloc so other code doesn't need to worry about uninitialized members. Drop the non-standard GFP flags, as we really don't want to fail the submit when under slight memory pressure. Remove one level of indentation by using an early return if the allocation failed. Also remove the unused drm device member.
