[PATCH 4.4 44/56] rfkill: gpio: fix memory leak in probe error path

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@xxxxxxxxxx>

commit 4bf01ca21e2e0e4561d1a03c48c3d740418702db upstream.

Make sure to free the rfkill device in case registration fails during
probe.
