| |
Simplify c2h_evt_hdl function by removing majority of its code. The function always returns _FAIL anyway, due to the wrapper function it calls always returning _FAIL. For this reason, it is better to just return _FAIL directly.
Leave the call to c2h_evt_read in place, as without it, event handling semantics of the driver would be changed, despite nothing actually being done with the event.
