Subject: gpio: mxc: Use devm_clk_get_optional instead of devm_clk_get
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7beb620f805dcb6757b5e7870bebd75e3e9b37e0;p=openwrt%2Fstaging%2Fblogic.git

gpio: mxc: Use devm_clk_get_optional instead of devm_clk_get

i.MX SoC's GPIO clock is optional, so it is better to use
devm_clk_get_optional instead of devm_clk_get.
