From 9ab981f22befda5524415db86ba83fd4188ceaee Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 11 Apr 2016 16:56:28 +0300 Subject: [PATCH] drm/i915: Use GEN5_IRQ_INIT() in vlv_display_irq_postinstall() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the hand rolled IMR/IER setup in vlv_display_irq_postinstall() with GEN5_IRQ_INIT(). Also rename the iir_mask to enable_mask to avoid consusion since we no longer deal with IIR here.
