Subject: [PATCH] drm/i915: Always call to intel_display_set_init_power() in resume_early.
Date: Tue, 16 Jan 2018 16:53:24 +0100	[thread overview]
Message-ID: <20180116155324.75120-1-maarten.lankhorst@linux.intel.com> (raw)

intel_power_domains_init_hw() calls set_init_power, but when using
runtime power management this call is skipped. This prevents hw readout
from taking place.
