Re: [PATCH 6/8] clk: rockchip: rk3528: Add SD/SDIO tuning clocks in GRF region

Hi,

+	nr_clks = rockchip_clk_find_max_clk_id(rk3528_clk_branches,
+					       nr_branches) + 1;
+
+	vo_grf = syscon_regmap_lookup_by_compatible("rockchip,rk3528-vo-grf");
+	if (!IS_ERR(vo_grf))
+		nr_clks = MAX(rockchip_clk_find_max_clk_id(rk3528_vo_clk_branches,
+							   nr_vo_branches) + 1,

drivers/clk/rockchip/clk-rk3528.c: In function 'clk_rk3528_probe':
drivers/clk/rockchip/clk-rk3528.c:1105:27: error: implicit declaration of function 'MAX'; did you mean 'MUX'?
 1105 |                 nr_clks = MAX(rockchip_clk_find_max_clk_id(rk3528_vo_clk_branches,
      |                           ^~~
      |                           MUX

It seems that missing definition with older kernels.

Thanks,
Chukun
