From 93de68f94081ea2cbc55e47dc84bcd606264050a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 11 Apr 2016 16:56:23 +0300 Subject: [PATCH] drm/i915: Remove "VLV magic" from irq setup MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit No clue what this is supposed to achieve.
