Help with input_report_key not reporting key

[Jose Diez <jose@mediacru.sh>]

Hello linux-input,

Sorry to post about a similar question again, but I'm still stuck. So a 
bit of back story: I'm writing a custom HID driver which, among other 
things, will register several input devices.

I'm able to read HID reports from the device using the raw_event 
callback, and I'm able to communicate with the device, but I seem to 
have hit an obstacle I can't get over. I've tried to add a proper input 
device to the driver, and while it registers it properly and shows up in 
/dev/input/*, the events seem to not go through.

I found this simple kernel module, which indeed works properly and 
reports key events: http://sprunge.us/NLcD

I then adapted it to work with my kernel module, shown here: 
http://sprunge.us/egIi

It allocates the input device in fblng_probe(), sets the KEY_A bit in 
the keybit field, and registers it. Then, when a request comes to the 
device, in fblng_event(), I (try to) send a key with input_report_key. 
This doesn't seem to trigger a keypress.

I'm looking at the relevant /dev/input/eventX with `evtest`. I know I'm 
getting events through, because I can see it in `dmesg`. However, it 
doesn't actually go through to the input handler.

Any help, please?

Thanks a lot,
Jose
