However, master->this is freed in\ni3c_master_detach_free_devs() before the master device itself is\nreleased.\n\nAs a result, sysfs accesses can dereference a freed master->this\npointer, leading to a use-after-free.\n\nKeep master->this alive until i3c_masterdev_release(), which is called\nafter the master device and its sysfs state are being torn down. Do not\nfree master->this as part of the normal device detach path.\n\nOn the error path in i3c_master_set_info(), reset master->this and\nbus.cur_master to NULL before freeing the allocated device.",
