This series implements an airplane-mode indicator LED trigger, which can be used by platform drivers. The default policy have have airplane-mode set when all the radios known by RFKill are OFF, and unset otherwise. This policy can be overwritten by one single userspace application at a time using the operations _AIRPLANE_MODE_INDICATOR_ACQUIRE and _AIRPLANE_MODE_INDICATOR_CHANGE. When the airplane-mode indicator state changes, userspace gets notifications through the RFKill control misc device (/dev/rfkill).
The series also contains a few general fixes and improvements to the subsystem. Additionally, I have a couple of patches to have this feature supported by the userspace tool 'rfkill' [1]. Should I use a different subject prefix to help separate those from kernel patches in linux-wireless?
