Sebastian Andrzej Siewior 52e0874fc1 locking/rt: Add sparse annotation PREEMPT_RT's sleeping locks. ...

The sleeping locks on PREEMPT_RT (rt_spin_lock() and friends) lack
sparse annotation. Therefore a missing spin_unlock() won't be spotted by
sparse in a PREEMPT_RT build while it is noticed on a !PREEMPT_RT build.

Add the __acquires/__releases macros to the lock/ unlock functions. The
trylock functions already use the __cond_lock() wrapper.
