From 15e72c1fc118731970ab1a94fb894039b8abfff4 Mon Sep 17 00:00:00 2001 From: Animesh Manna Date: Wed, 28 Oct 2015 23:59:05 +0200 Subject: [PATCH] drm/i915/gen9: Use flush_work to synchronize with dmc loader During driver unload to ensure we dont have any pending task, flush_work added to complete firmware loading task. v1: Initial version. v2: As per review comments from Daniel, Removed flush_work from skl_set_power_well. As we have taken power well refernece and rpm count during firmware loading by using display_power_domain_get/put - this will always ensure rpm will be blocked if firmware is not loaded.
