[PATCH v9 06/12] iommu/arm-smmu-v3: Handle gerror during suspend

[Jason Gunthorpe]

> The GERROR register's state might be lost when the SMMU is powered down
> during runtime suspend. Handle any pending errors before suspending.
> 
> Refactor the gerror handling logic into a helper function and invoke it
> from the runtime suspend callback after disabling the SMMU. This ensures
> that any late-breaking gerrors are logged and ack'ed before the hardware
> state is lost.

The commit message isn't clear, this is just a refactoring patch it
does not "Handle gerror during suspend"

But the refactoring is fine

Though sashiko seems right about the pre-existing bug.
