Revert "rfkill: remove dead code"
This reverts commit 2e48928d8a0f38c1b5c81eb3f1294de8a6382c68. Those functions are needed and should not be removed, or there is no way to set the rfkill led trigger name. Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
