From 65f42cdc6e654543a769a5f4df060ae00096a334 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Wed, 10 Apr 2019 16:53:43 -0700 Subject: [PATCH] drm/i915: convert the IRQ initialization functions to intel_uncore MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The IRQ initialization helpers are simple and self-contained. Continue the transition started in the recent uncore rework to get us rid of I915_READ/WRITE and the implicit dev_priv variables. While the implicit dev_priv is removed from the IRQ initialization helpers, we didn't get rid of them in the macro callers. Doing that should be very simple now. v2: Rebase on top of the new patches.
