From 12e49feadff6d7b7ebbe852b36943a71524d8d34 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Thu, 7 May 2015 15:19:25 +0200 Subject: [PATCH] drm/radeon: stop trying to suspend UVD sessions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Saving the current UVD state on suspend and restoring it on resume just doesn't work reliable. Just close cleanup all sessions on suspend.
