Subject: mtd: nand: mxc_nand: Remove unneeded check for platform_get_resource()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=96f2a4a1a77a60a55cc15e13938bd3f2d0ee86bc;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: mxc_nand: Remove unneeded check for platform_get_resource()

devm_ioremap_resource() checks its arguments, so there is no need for
explicitly checking the return value from platform_get_resource().
