From 9b2e8c9411a81daf4772fbe30e0953f781f9b440 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 30 Oct 2014 19:43:01 +0200 Subject: [PATCH] drm/i915: Drop useless VLV_IIR writes from vlv_display_irq_postinstall() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The extra VLV_IIR writes at the end of vlv_display_irq_postinstall() serve no purpose. Remove them. The VLV_IMR/IER/IIR setup at the start of the function also seems a bit pointless since it doesn't unmask/enable anything. But leave it be for now.
