drm/amd/display: add virtual_setup_stream_attribute decl to header

2022-04-19T17:58:32+00:00

Smatch reports this issue virtual_link_hwss.c:32:6: warning: symbol 'virtual_setup_stream_attribute' was not declared. Should it be static? virtual_setup_stream_attribute is only used in virtual_link_hwss.c, but the other functions in the file are declared in the header file and used elsewhere. For consistency, add the virtual_setup_stream_attribute decl to virtual_link_hwss.h. Signed-off-by: Tom Rix Signed-off-by: Alex Deucher
