Add additional examples in Documentation/spinlocks.txt
Checkpatch will throw an error if code doesn't use the correct initializers for static spinlocks: ERROR: Use of SPIN_LOCK_UNLOCKED is deprecated: see Documentation/spinlocks.txt This is fine, but Documentation/spinlocks.txt isn't very clear on how to _use_ the new initializers for static variables. To save people time in the future, I added two small examples of how to fix old-style static initializers to be more lockdep friendly.
