Subject: [PATCH v2 10/12] checkpatch: Deprecate srcu_read_lock_lite() and srcu_read_unlock_lite()

Uses of srcu_read_lock_lite() and srcu_read_unlock_lite() are better
served by the new srcu_read_lock_fast() and srcu_read_unlock_fast() APIs.
As in srcu_read_lock_lite() and srcu_read_unlock_lite() would never have
happened had I thought a bit harder a few months ago.  Therefore, mark
them deprecated.
