RFC about new device ioctl

[Roland M. <rm...@gm...>]

Hi,

to solve the problem described below, I suggest to create a new ioctl
LIRC_NOTIFY_DECODE. The idea in principle is to give feedback to the
user about if an IR signal was decoded an put to the queue successfully.
I don't belive that the provided patch breaks anything.

                {

hw.ioctl_func(LIRC_NOTIFY_DECODE, NULL);

                        for (i=0; i<clin; i++)

I'm not sure if this is useful for any other hardware (maybe there is an
way to extend the homebrew serial receiver with an LED to get feedback).
What about mceusb devices?
