Repeat all pending events, to prevent axis sticking

[StelardActek]

I found this issue when testing some code derived from yours. It would be really easy to get the axes on the virtual device to stick by rapidly releasing the real pedals. By looping until all pending events are read, the issue goes away.

Thanks for this. I think it would be tidier to put the libevdev_next_event call in the while condition. It also looks like LIBEVDEV_READ_FLAG_NORMALshould be included in the flags.

while (libevdev_next_event(real, LIBEVDEV_READ_FLAG_NORMAL | LIBEVDEV_READ_FLAG_BLOCKING, &ev) == 0) {
	write(uifd, &ev, sizeof(ev));
}

I'm currently unable to test if this but I've pushed the commit to https://github.com/sambazley/virtjs/tree/StelardActek-master

Agreed, that is much neater.
