Update our copies of the brcm2708 patches to the latest rpi-3.10-y rebased against linux-3.10.y stable (3.10.32). This should hopefully make it easier for us in the future to leverage the raspberry/rpi-* branches. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39770

Subject: [PATCH 125/174] clockevents: Add module refcount
|
|
|
|
commit ccf33d6880f39a35158fff66db13000ae4943fac upstream.
|
|
|
|
We want to be able to remove clockevent modules as well. Add a
|
|
refcount so we don't remove a module with an active clock event
|
|
device.
