This series adds a drmm_release_action function (which is similar to devres devm_release_action) and a simple test that uses it. v1 -> v2: - Split the test changes (Maxime) - Simplify priv lifetime management (Maxime) v2 -> v3: - Order tests alphabetically (Maxime) - Add comments explaining the intention behind the tests and the reason why DRM device can't be embedded inside test priv (Maxime) - Bring back priv lifetime management from v1 to avoid use-after-free Michał Winiarski (3): drm/managed: Add drmm_release_action drm/tests: managed: Extract device initialization into test init drm/tests: managed: Add a simple test for drmm_managed_release drivers/gpu/drm/drm_managed.c | 39 ++++++++++++ drivers/gpu/drm/tests/drm_managed_test.c | 80 +++++++++++++++++++----- include/drm/drm_managed.h | 4 ++ 3 files changed, 108 insertions(+), 15 deletions(-)
