drm/tests: shmem: Fix memleak

2025-04-29T15:28:28Z

The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using the drm_gem_shmem_get_sg_table() function and rightfully calls sg_free_table() on it. However, it's also supposed to kfree() the returned sg_table, but doesn't. This leads to a memory leak, reported by kmemleak. Fix it by adding a kunit action to kfree the sgt when the test ends.

drm/tests: probe-helper: Fix drm_display_mode memory leak

drm_analog_tv_mode() and its variants return a drm_display_mode that needs to be destroyed later one.

drm/tests: helpers: Create kunit helper to destroy a drm_display_mode

2025-04-08T15:26:58Z

A number of test suites call functions that expect the returned drm_display_mode to be destroyed eventually. However, none of the tests called drm_mode_destroy, which results in a memory leak. Since drm_mode_destroy takes two pointers as argument, we can't use a kunit wrapper. Let's just create a helper every test suite can use.
