2025-02-25drm/amdgpu: Remove unused nbif_v6_3_1_sriov_funcsDr. David Alan Gilbert
The nbif_v6_3_1_sriov_funcs instance of amdgpu_nbio_funcs was added in commit 894c6d3522d1 ("drm/amdgpu: Add nbif v6_3_1 ip block support") but has remained unused. Alex has confirmed it wasn't needed. Remove it, together with the four unused stub functions: nbif_v6_3_1_sriov_ih_doorbell_range nbif_v6_3_1_sriov_gc_doorbell_init nbif_v6_3_1_sriov_vcn_doorbell_range nbif_v6_3_1_sriov_sdma_doorbell_range Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
