[PATCH] clk: renesas: rcar-gen3: Fix error return code in cpg_sd_clock_recalc_rate

[Yoshihiro Kaneko <ykaneko0929@gmail.com>]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

In .recalc_rate of struct clk_ops, it is desirable to return 0 if an
error occurs, but -EINVAL is returned. This patch fixes it.
