From 90d7cd240308e3d77c414224c47f42f2362c3e21 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 12 Jun 2017 12:21:14 +0200 Subject: [PATCH] drm/i915: Pass connector state to intel_panel_set_backlight_acpi MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Passing the state is also needed to convert the backlight functions to use the correct state instead of looking it up. This is done as a separate commit to allow easier bisecting.
