[Nouveau] [PATCH NEW 5/9] acpi: Use a single type of errors in evaluate functions

[Pierre Moreau]

I wasn't sure how to insert this one into the flow, if I should make it a patch 4.5 or not. I went with patch 5, so all the following patches are incremented by 1 compared to the v1, sorry about that.
What should be the way to go?

Pierre
