Linux 6.15-rc5, requested by tzimmerman for fixes required in drm-next.

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.

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.

The find_preferred_mode() functions takes the mode_config mutex, but due
to the order most tests have, is called with the crtc_ww_class_mutex
taken. This raises a warning for a circular dependency when running the

has been created to avoid the issue.

The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug
logging in case the passed in link rate or lane count are zero. There's
no further error checking as such, and the function returns 0.
There should be no case where the parameters are zero. The returned
value is generally used as a divisor, and if we were hitting this, we'd
be seeing division by zero.
Just remove the debug logging altogether, along with the mgr parameter,
so that the function can be used in non-MST contexts without the
topology manager.
v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre)
