Overall it looks good.

There are a few check-git log and check-patch errors. Please send the
next version with fixes that makes sense.

If there are no more review comments. I will pull the next version in a week for
eventdev-next.

Wrong headline prefix:
	drivers: add bus dependency for event
	fslmc/bus: add interrupt enabling routine

### bus/fslmc: enable portal interrupt handling
