Subject: PCI: mvebu: Remove unneeded gpiod NULL check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c3539516538006a92fa395cf8b203a23a6913567;p=openwrt%2Fstaging%2Fblogic.git

PCI: mvebu: Remove unneeded gpiod NULL check

The gpiod API checks for NULL descriptors, so there is no need to duplicate
the check in the driver.
