This is a version of irq_create_of_mapping() that propagates the precise
error code instead of returning 0 for all errors. It will be used in
subsequent patches to allow further propagation of error codes.

To avoid code duplication, implement irq_create_of_mapping() as a
wrapper around the new __irq_create_of_mapping().

This function is a manageable number of callers that the callers should
just be updated and avoid the wrapper.

I second this and also don't want the first patch to use a wrapper.
