sparse bogus unexpected unlock warning? untag_chunk

[Richard Guy Briggs]

After adding "C=1 CF=-D__CHECK_ENDIAN__" to my build script, sparse
produced the following warning:
	kernel/audit_tree.c:222:13: warning: context imbalance in 'untag_chunk' - unexpected unlock

It looks like a confused parser to me, because the locks appear to
balance properly from my review.

It doesn't say which lock triggered the warning, hash_lock, or
entry->lock.  The hash_lock is locked on call and returns in the same
state.  entry->lock looks fine.  The fsnotify marks look get/put
balanced too.

Is sparse spewing bogons, or am I?
