Subject: drm/amd/display: don't initialize result
Git-commit: d6258eaa41fc531277d44fbbee670c866025bfdc
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The wrong enum type is used to initialize the result, leading to a
warning when using clang:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:1998:26: warning:
      implicit conversion from enumeration type 'enum ddc_result' to different
      enumeration type 'enum dc_status' [-Wenum-conversion]
        enum dc_status result = DDC_RESULT_UNKNOWN;
                       ~~~~~~   ^~~~~~~~~~~~~~~~~~
1 warning generated.

Initialization of result is unnecessary anyway, just drop the
initialization.
