From c2b66797cf34e4bc677c3a7cbb9ca5b1060031a1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 30 Oct 2014 19:43:02 +0200 Subject: [PATCH] drm/i915: Use vlv display irq setup code for chv MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Throw away the hand rolled display irq setup code on chv, and instead just call vlv_display_irq_postinstall() and vlv_display_irq_uninstall().
