[PATCH 3.12 40/60] bcma: use (get|put)_device when probing/removing device driver

From: Jiri Slaby
Date: Tue Mar 14 2017 - 09:25:00 EST


From: RafaÅ MiÅecki <rafal@xxxxxxxxxx>

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

===============

commit a971df0b9d04674e325346c17de9a895425ca5e1 upstream.

This allows tracking device state and e.g. makes devm work as expected.
