Subject: mtd: nand: mxc_nand: Check the return value from clk_prepare_enable()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dcedf628f55ccdb34c8783a03bed9382bb5e1a82;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: mxc_nand: Check the return value from clk_prepare_enable()

clk_prepare_enable() may fail, so let's check its return value and propagate it
in the case of error.
