drivers/ata/libata-eh: Add smp_mb() before spin_unlock_wait() Many spin_unlock_wait() implementations do not provide release semantics and it is not clear that this use case does not require them. This commit therefore adds an smp_mb() before the spin_unlock_wait() to ensure that any needed release semantics are provided.
