The iommu->lock is used to protect the per-IOMMU domain ID resource.
Move the spinlock acquisition/release into the helpers where domain
IDs are allocated and freed. The device_domain_lock is irrelevant to
domain ID resources, remove its assertion as well.
while moving the lock you also replace spin_lock_irqsave() with spin_lock().
It'd be cleaner to just do movement here and then replace all _irqsave()
in patch 8.
Yeah, that will be clearer.
Best regards,
baolu
