macintosh: fix possible memory leak in macio_add_one_device()
[ Upstream commit 5ca86eae55a2f006e6c1edd2029b2cacb6979515 ]
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically. It
needs to be freed when of_device_register() fails. Call put_device() to
give up the reference that's taken in device_initialize(), so that it
can be freed in kobject_cleanup() when the refcount hits 0.
macio device is freed in macio_release_dev(), so the kfree() can be
removed.
Fixes: 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array")
