From de3ded0ae677749b4fc9f59d15b26b9f077340ac Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 2 Oct 2017 11:04:16 +0100 Subject: [PATCH] drm/i915: Silence compiler warning for hsw_power_well_enable() Not all compilers are able to determine that pg is guarded by wait_fuses and so may think that pg is used uninitialized.
