Subject: [PATCH 0/2] input - leds: fix bugs found by fuzzing

Hi,

Peter wrote a fuzzing uinput program[1] to check on libinput,
and the result is that the kernel fails more often than
libinput :)

These 2 patches allow to fix the early failures.

I marked them as stable as I believe eventhough not many
people discovered those and reported them, they should
still be fixed in current kernels.

The fuzzing process still manages to crash the kernel,
bu I have the feeling those crashes are now related
to some races between other userspace process that attempt
to handle the spurious events injected in those random
devices. For instance, the KEY_BLUETOOTH or RF_KILL seem
to manage to mess up my network driver.

Cheers,
Benjamin
