From: Imre Deak Date: Thu, 24 Jul 2025 09:02:37 +0000 (+0300) Subject: drm/i915: Fix selecting CONFIG_DRM_KUNIT_TEST in debug builds X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=16d2a92e7ec8c7828069f86a0aa7974acafb7e57;p=users%2Fwilly%2Fxarray.git drm/i915: Fix selecting CONFIG_DRM_KUNIT_TEST in debug builds Selecting an option which depends on other options only works if the dependencies are guaranteed to be selected (as these dependencies will not be automatically selected). CONFIG_DRM_KUNIT_TEST depends on DRM, MMU and KUNIT the first two of which are guaranteed to be selected for i915, but the last one is not. Hence, selecting CONFIG_DRM_KUNIT_TEST in i915 debug builds may result in CONFIG_DRM_KUNIT_TEST being selected without the CONFIG_KUNIT dependency being selected. This causes at least the following compile error: drivers/gpu/drm/tests/drm_bridge_test.c: In function ‘drm_test_bridge_alloc_init’: drivers/gpu/drm/tests/drm_bridge_test.c:449:21: error: implicit declaration of function ‘kunit_device_register’; did you mean ‘root_device_register’? [-Werror=implicit-function-declaration] 449 | priv->dev = kunit_device_register(test, "drm-bridge-dev"); Fix the above by selecting CONFIG_DRM_KUNIT_TEST only if CONFIG_KUNIT is also selected.
