From c3ce9d8fd404ca1d4697a104ce4899525dd43c51 Mon Sep 17 00:00:00 2001 From: Adel Gadllah Date: Fri, 1 May 2015 17:43:41 +0200 Subject: [PATCH] modesetting: Fix software cursor fallback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code in drmmode_set_cursor does not properly handle the case where drmModeSetCursor2 returns any other error than EINVAL and silently fails to set a cursor. So only return when the drmModeSetCursor2 succeeds (i.e returns 0) and disable the cursor2 usage on EINVAL.
