There's no reason to store the return value of rockchip_emmc_phy_power() in a variable nor to check it. Just return it. Signed-off-by: Douglas Anderson <dianders@chromium.org> --- Changes in v2: - Move code cleanup before set phyctrl_frqsel based on card clock (Shawn)
Looks good to me. Reviewed-by: Shawn Lin <shawn.lin@rock-chips.com>
