From 2a7d3d6d5ddbd202c09f228829cd03609a8efb23 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 12 Aug 2015 17:00:24 +0200 Subject: drm/irq: Remove negative CRTC index special-case The drm_send_vblank_event() function treats negative CRTC indices as meaning that a driver doesn't have proper VBLANK handling. This is the only place where DRM needs negative CRTC indices, so in order to enable subsequent cleanup, remove this special case and replace it by the more obvious check for whether or not VBLANK support was initialized.
