Tiezhu Yang 8e69ac0440 test_kmod: avoid potential double free in trigger_config_run_type() ... [ Upstream commit 0776d1231bec0c7ab43baf440a3f5ef5f49dd795 ] Reset the member "test_fs" of the test configuration after a call of the function "kfree_const" to a null pointer so that a double memory release will not be performed.
