Hi Dmitry,
What happens if interrupts comes as soon as you have done the key_init(..)
here? I see that you are registering the input device after it, right? Looks
like you should do this at the end of probe?
It should be fine, input devices properly allocated (with
input_allocate_device() or devm- version) are able to accept events even
if input device has not been registered yet. It is and advertised
feature:
drivers/input/input.c:
"
* input_event() - report new input event
...
* NOTE: input_event() may be safely used right after input device was
* allocated with input_allocate_device(), even before it is registered
* with input_register_device(), but the event will not reach any of the
* input handlers. Such early invocation of input_event() may be used
* to 'seed' initial state of a switch or initial position of absolute
* axis, etc.
Thanks. Looks good since input_allocate_device(...) is called before the
init.
