Subject: phy: rockchip-emmc: Minor code cleanup in rockchip_emmc_phy_power_on/off()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=352051ef1ff5efa8ba050bc3a581dbf136a1f97b;p=linux-beck.git

phy: rockchip-emmc: Minor code cleanup in rockchip_emmc_phy_power_on/off()

There's no reason to store the return value of rockchip_emmc_phy_power()
in a variable nor to check it.  Just return it.
