building with gcc and W=1 reports
drivers/gpu/drm/amd/amdgpu/umc_v8_10.c:437:37: error: variable ‘channel_index’
  set but not used [-Werror=unused-but-set-variable]
  437 |         uint32_t eccinfo_table_idx, channel_index;
      |                                     ^~~~~~~~~~~~~

channel_index is not used so remove it.
