From 332857fdac73f1c7b74ad962c07bb39e4c0c145a Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 16 Oct 2024 14:20:15 -0700 Subject: [PATCH] of: Allow overlay kunit tests to run CONFIG_OF_OVERLAY=n Some configurations want to enable CONFIG_KUNIT without enabling CONFIG_OF_OVERLAY. The kunit overlay code already skips if CONFIG_OF_OVERLAY isn't enabled, so this select here isn't really doing anything besides making it easier to run the tests without them skipping. Remove the select and move the config setting to the drivers/of/.kunitconfig file so that the overlay tests can be run with or without CONFIG_OF_OVERLAY set to test either behavior.
