[PATCH v3 0/6] resource: introduce union(), intersection() API

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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 v3:
- rebased on top of v5.10-rc1
- dropped upstreamed dependencies
- added Rb tag to the last patch (Mika)

Andy Shevchenko (6):
  resource: Simplify region_intersects() by reducing conditionals
  resource: Group resource_overlaps() with other inline helpers
  resource: Introduce resource_union() for overlapping resources
  resource: Introduce resource_intersection() for overlapping resources
  PCI/ACPI: Replace open coded variant of resource_union()
  ACPI: watchdog: Replace open coded variant of resource_union()
