[POWERPC] Demacrofy arch/powerpc/platforms/maple/pci.c
Noticed that the U3_*CFA macros have some typos: #define U3_HT_CFA0(devfn, off) \ ((((unsigned long)devfn) << 8) | offset) (refers to offset rather than off) #define U3_AGP_CFA0(devfn, off) \ ((1 << (unsigned long)PCI_SLOT(dev_fn)) \ | (((unsigned long)PCI_FUNC(dev_fn)) << 8) \ (refers to dev_fn rather than devfn) Things happen to work, but there doesn't seem to be any reason these shouldn't be functions. Overall behavior should be unchanged. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
