[PATCH V2 4/5] bcma: connect the bcma bus suspend/resume to the bcma driver suspend/resume

From: Rafał Miłecki <zajec5@gmail.com>
Date: 2012-01-13 22:59:01
Subsystem: broadcom specific amba driver (bcma), networking drivers (wireless), the rest · Maintainers: Rafał Miłecki, Johannes Berg, Linus Torvalds

From: Linus Torvalds <torvalds@linux-foundation.org>

Now the low-level driver actually gets informed that it is getting suspended and resumed.
