[PATCH] amdgpu/dc: Remove unnecessary initialization in dc_link_handle_hpd_rx_irq()

[Matthias Kaehlcke]

The initialization of 'result' is unnecessary, the variable is assigned
unconditionally a few lines below. Removing the initialization also fixes
the following warning when building with clang:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:1931:26:
  error: implicit conversion from enumeration type 'enum ddc_result'
  to different enumeration type 'enum dc_status' [-Werror,-Wenum-conversion]
    enum dc_status result = DDC_RESULT_UNKNOWN;
