Summary

Comparable to the current situation. Minor savings, one caller simply
passes the count directly through.

This works well with D35519/D35529/D35546. The whole stack turns to returning stray counts, which are rather more useful than 0 or EINVAL. Notably for a PPI interrupt, limited reporting of strays can be rather more consistent.

A more recent version of the series is now on Github as #1301. Note that is marked as a draft since something else is higher priority right now.
