From 60ccc38f53ad50128bf33616f4e1745947eb726c Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 10 Jan 2018 10:32:18 +0100 Subject: [PATCH] Revert "drm/atomic: Fix memleak on ERESTARTSYS during non-blocking commits" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This reverts commit a10195bbe7f4e6ba540083ba13126ef745116cae. This commit needs some more thought, and is currently crashing kms_flip tests. Until we figure out what's going wrong it's better to revert, and also next time apply it to drm-misc-fixes.
