Subject: leds: class: Make led_remove_lookup() NULL-aware
X-Git-Url: http://git.ipfire.org/index.cgi?a=commitdiff_plain;h=7a43ccf85dfe06eef483c034e68b81ff326741aa;p=thirdparty%2Flinux.git

leds: class: Make led_remove_lookup() NULL-aware

It is a usual pattern in the kernel to make releasing functions be NULL-aware
so they become a no-op. This helps reducing unneeded checks in the code where
the given resource is optional.
