[PATCH 0/4] Simplify event handling logic in input core

[Dmitry Torokhov]

This series tries to untangle somewhat convoluted logic in the input
event processing in the input core by realizing that input handler can
be either a filter, or a handler that handles a single event at a time,
or a handler that can handle a sequence of events, but should not mix
the 3 behaviors in one handler. This allows us to reduce both filter
functionality and single-event handling functionality to batch handling
and have the main event handling path to only deal with
input_handle->events() batch method.

Dmitry Torokhov (4):
  Input: make sure input handlers define only one processing method
  Input: make events() method return number of events processed
  Input: simplify event handling logic
  Input: preallocate memory to hold event values
