Since fa3cdf8d0b09 ("drm/nouveau: Reset MST branching unit before

Since then clearing DP_MST_CTRL in nv50_mstm_new() has been unnecessary
and redundant, so let's remove it.Signed-off-by: Lyude Paul <[email protected]> Reviewed-by: Ben Skeggs <[email protected]> --- drivers/gpu/drm/nouveau/dispnv50/disp.c | 11 ----------- 1 file changed, 11 deletions(-) diff --git a/drivers/gpu/drm/nouveau/dispnv50/disp.c b/drivers/gpu/drm/nouveau/dispnv50/disp.c index e7874877da858..c4d138f0ca054 100644 --- a/drivers/gpu/drm/nouveau/dispnv50/disp.c +++ b/drivers/gpu/drm/nouveau/dispnv50/disp.c @@ -1535,17 +1535,6 @@ nv50_mstm_new(struct nouveau_encoder *outp, struct drm_dp_aux *aux, int aux_max, struct drm_device *dev = outp->base.base.dev; struct nv50_mstm *mstm; int ret; - u8 dpcd; - - /* This is a workaround for some monitors not functioning - * correctly in MST mode on initial module load.
