From 5f057ffd6da26c939dff976a2acc76233bbe4467 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Thu, 13 Jul 2017 18:25:25 +0200 Subject: [PATCH] drm: rename, adjust and export drm_atomic_replace_property_blob Git-commit: 5f057ffd6da26c939dff976a2acc76233bbe4467 Patch-mainline: v4.14-rc1 References: FATE#322643 bsc#1055900 The function has little to do with atomic, it's just where it has so far been needed. So, rename it to drm_property_replace_blob, move it to drm_property.c and export it. Change the semantics to return whether the blob was replaced instead of using an extra argument for that.
