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

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.
