Subject: [ 27/79] alx: fix lockdep annotation

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

------------------

From: Maarten Lankhorst <maarten.lankhorst@...onical.com>

[ Upstream commit a8798a5c77c9981e88caef1373a3310bf8aed219 ]

Move spin_lock_init to be called before the spinlocks are used, preventing a lockdep splat.
