Subject: [PATCH v2] drm/i915: Avoid enum conversion warning
Date: Sun, 26 Nov 2017 19:49:14 -0800	[thread overview]
Message-ID: <20171127034914.2291-1-nick.desaulniers@gmail.com> (raw)

Fixes the following enum conversion warning:

drivers/gpu/drm/i915/intel_ddi.c:1481:30: error: implicit conversion
from enumeration type 'enum port' to different enumeration type 'enum
intel_dpll_id' [-Werror,-Wenum-conversion]
        enum intel_dpll_id pll_id = port;
                           ~~~~~~   ^~~~
