Sorry about that. I started out by using devm_ioremap_resource, which
uses the in-band error signaling, and forgot to match the guard when I
changed it.
I see that this was reported by your CI, do you mind me asking what it
is running in the back-end? At least my version of sparse does not seem
to catch this.
