Call spin_lock_init() before the spinlocks are used, both in early init 
and probe functions preventing a lockdep splat.

I have been observing lockdep complaining [1] during boot on my a80 optimus [2]
when CONFIG_PROVE_LOCKING has been enabled. This patch resolves the splat,
and has been tested on a few other sunxi platforms without issue.

Not entirely sure what to do with this one. You sent it to:arm at kernel.org, but
it should probably have gone to Philipp?

We can pick it up with an ack from him though, no problem.

I have applied the patch here:

    git://git.pengutronix.de/git/pza/linux reset/for_v3.19

I was going to send a pull request tonight, but since I don't have any
other pending fixes besides this, and you already offered to pick it up,

Applied to arm-soc/fixes with ack from Philipp.

Thanks,

Kevin
