Tetsuo Handa e05dd56499 driver core: Don't ignore class_dir_create_and_add() failure. ... commit 84d0c27d6233a9ba0578b20f5a09701eb66cee42 upstream. syzbot is hitting WARN() at kernfs_add_one() [1]. This is because kernfs_create_link() is confused by previous device_add() call which continued without setting dev->kobj.parent field when get_device_parent() failed by memory allocation fault injection. Fix this by propagating the error from class_dir_create_and_add() to the calllers of get_device_parent().
