why?
because if the led_classdev_register fails we wont do gpio free
because using devm_ functions, there is no need for error paths

Bryan,

This patch is not even compile tested, since my machine crashed, and
didn't have the ARM toolchain, sorry ..

And i think this patch is legit not as that pci_set_drvdata one :(
