Subject: sparc/PCI: Use helper functions to access fields in struct msi_desc
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3bf15f53c963a43c317e65e1709e9f020c04f024;p=linux-beck.git

sparc/PCI: Use helper functions to access fields in struct msi_desc

Use helper functions to access fields in struct msi_desc, so we could
easily refine struct msi_desc later.
