From: Rodrigo Siqueira <rodrigo.sique...@amd.com>
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().
