[PATCH v1 3/6] powerpc: Set I/O port resource types correctly

From: Bjorn Helgaas
Date: Mon Dec 04 2017 - 19:40:35 EST


From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

Set I/O port resource structs to have IORESOURCE_IO in their type field.

Previously we marked these as merely IORESOURCE_BUSY without indicating the
type. Setting the type doesn't fix any functional problem but makes %pR
on the resource work better.
