 drivers/gpu/drm/amd/amdgpu/cz_ih.c:223: warning: Function parameter or member 'ih' not described in 'cz_ih_decode_iv'
 drivers/gpu/drm/amd/amdgpu/cz_ih.c:223: warning: Function parameter or member 'entry' not described in 'cz_ih_decode_iv'
 drivers/gpu/drm/amd/amdgpu/cz_ih.c:253: warning: Function parameter or member 'ih' not described in 'cz_ih_set_rptr'
