If anyone has any objections, please let me know. ------------------ From: Lu Baolu [ Upstream commit 9a16ab9d640274b20813d2d17475e18d3e99d834 ] In the iommu probe_device path, domain_context_mapping() allows setting up the context entry for a non-PCI device. However, in the iommu release_device path, domain_context_clear() only clears context entries for PCI devices. Make domain_context_clear() behave consistently with domain_context_mapping() by clearing context entries for both PCI and non-PCI devices.
