Maxime Ripard e733f3e9dc drm/vc4: tests: Fix UAF in the mock helpers ... [ Upstream commit cdcd6aef9d ] The VC4 mock helpers allocate the CRTC, encoders and connectors using a call to kunit_kzalloc(), but the DRM device they are attache to survives for longer than the test itself which leads to use-after-frees reported by KASAN. Switch to drmm_kzalloc to tie the lifetime of these objects to the main DRM device.
