Which ever makes sense visually, here '='.

pps_sdp->pps_payload.pps_4 =
	dsc_cfg->bits_per_pixel >> X << DSC_PPS_MSB_SHIFT |
	dsc_cfg->vbr_enable << DSC_PPS_VBR_EN_SHIFT |
	dsc_cfg->enable422 << DSC_PPS_SIMPLE422_SHIFT |
	dsc_cfg->convert_rgb << DSC_PPS_CONVERT_RGB_SHIFT |
	dsc_cfg->block_pred_enable << DSC_PPS_BLOCK_PRED_EN_SHIFT;

If you want to mask with 0xff do it without having to refer to C type promotion
rules.

And they all need updating, eventually. There's no reason for new file
to use the old style.

No, the code is MIT. You replace the licence with just a SPDX link.
