drm/amd/display: Remove useless assignments

2024-10-15T15:22:48Z

[WHAT & HOW] "split_pipe" are assigned to test_pipe and then immediately are updated to other values. The same also applies to "status" as well. Similarly, "id", "dwb" and "unused_dpps" are assigned but the functions immediately return, and thus they have no effects. As a results, the assignments removed. This fixes 5 UNUSED_VALUE issues reported by Coverity. Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Hung Signed-off-by: Roman Li Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

This fixes 12 NO_EFFECT issues reported by Coverity. Reviewed-by: Harry Wentland Acked-by: Zaeem Mohamed Signed-off-by: Alex Hung Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
