Fix the following Wstringop-overflow warnings when building with GCC-11:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:493:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:493:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:493:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:388:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:388:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dpia.c:388:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:1491:17: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:2613:25: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=] drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:2613:25: warning: ‘dp_decide_lane_settings’ accessing 4 bytes in a region of size 1 [-Wstringop-overflow=]
by removing the over-specified array size from the argument declarations.
This helps with the ongoing efforts to globally enable -Wstringop-overflow.
