[ CC Dmitry Torokhov (linux-input maintainer) plus linux-input ML ]

By looking at my screenshot, someone could imagine that there is a
problem coming from the input GIT branch(es) merges:

input_to_handler()
input_pass_values()
input_handle_event()
input_event()

Unfortunately, with those 3 revert-patches I see the same kernel-panic.

Dimitry, any idea what can cause this kernel-panic?
