Subject: resource: introduce is_type_match() helper and use it
Date: Wed, 25 Sep 2024 18:43:35 +0300

There are already a couple of places where we may replace a few lines of
code by calling a helper, which increases readability while deduplicating
the code.

Introduce is_type_match() helper and use it.
