While addressing the bugs reported by the smatch tool, I saw that pe is
not
being used at the moment.
412 static void _dpu_hw_sspp_setup_scaler3(struct dpu_hw_pipe *ctx,
413 struct dpu_hw_pipe_cfg *sspp,
414 struct dpu_hw_pixel_ext *pe,
415 void *scaler_cfg)
416 {
417 u32 idx;
418 struct dpu_hw_scaler3_cfg *scaler3_cfg = scaler_cfg;
419
420 (void)pe;
421 if (_sspp_subblk_offset(ctx, DPU_SSPP_SCALER_QSEED3, &idx) || !sspp
422 || !scaler3_cfg || !ctx || !ctx->cap || !ctx->cap->sblk)
423 return;
424
425 dpu_hw_setup_scaler3(&ctx->hw, scaler3_cfg, idx,
426 ctx->cap->sblk->scaler_blk.version,
427 sspp->layout.format);
428 }
As part of this change, can you please drop this?
