From: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> When calling the dc_link_bw_kbps_from_raw_frl_link_rate_data from amdgpu_dm, GCC highlighted the following issue: In function ‘get_conv_frl_bw’: error: passing argument 1 of ‘dc_link_bw_kbps_from_raw_frl_link_rate_data’ discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] 997 | aconnector->dc_link->dc, This commit fix this issue by making DC a constant variable since we only use it to invoke the function bw_kbps_from_raw_frl_link_rate_data().
