Make it possible to load lirc program type with just CAP_BPF. There is nothing exceptional about lirc programs that means they require SYS_CAP_ADMIN. In order to attach or detach a lirc program type you need permission to open /dev/lirc0; if you have permission to do that, you can alter all sorts of lirc receiving options. Changing the IR protocol decoder is no different. Right now on a typical distribution /dev/lirc devices are only read/write by root. Ideally we would make them group read/write like other devices so that local users can use them without becoming root.
