1) Change pr_warn()s to pr_err()s. These messages are actually
errors and not warnings.
2) Add missing \n.
3) Error message for kzalloc() failure is removed per suggestion
by Joe Perches. There is generic stack_dump() for allocation issues.

Some of the braces around single statements
could also be removed.

could be written:

 	evt = kzalloc(sizeof(*evt), GFP_KERNEL);
	if (!evt)
		return;

etc...
