[PATCH v6 0/7] resource: introduce union(), intersection() API

From: Andy Shevchenko
Date: Tue Nov 03 2020 - 16:55:25 EST


Some users may want to use resource library to manage their own resources,
besides existing users that open code union() and intersection()
implementations.

Provide a generic API for wider use.

Changelog v6:

- Cc'ed to LKML and Greg (Rafael)
