From ed4f885657fe7e9bfec3d86a2b426da1e0d0c5de Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 8 Jun 2016 14:18:54 +0200 Subject: [PATCH] drm/arc: Nuke event_list This is just used for cleanup in preclose, and with the reworked event handling code this is now done properly by the core. Nuke it! But it also shows that arc totally fails at sending out drm events for flips. Next patch will hack that up. v2: Rebase it!
