[ Upstream commit a91eb6803c1c715738682fece095145cbd68fe0b ]
In qcom_iommu_has_secure_context(), we should call of_node_put()
for the reference 'child' when breaking out of for_each_child_of_node()
which will automatically increase and decrease the refcount.
Fixes: d051f28c8807 ("iommu/qcom: Initialize secure page table")
