6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx> [ Upstream commit fd9fe654f41c0271dbfe55d975c6d1bfa88820fb ] In preparation for commonizing topckgen probe on various MediaTek SoCs clock drivers, add the ability to register the MFG MUX notifier in mtk_clk_simple_probe() by passing a custom notifier register function pointer, as this function will be slightly different across different SoCs.
