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

[Jiri Slaby]

From: Rafał Miłecki <ra...@milecki.pl>

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.
