This function is only ever used as a pointer passed to
pci_bus_alloc_resource()?
What about having
#ifndef pcibios_fixup_bus
#define pcibios_fixup_bus NULL
#endif
in asm-generic/pci.h, letting the architecture with a non-trivial
implementation predefine the preprocessor symbol, and teaching
pci_bus_alloc_resource() to handle NULL?
[...]
Oh, the latter eventually calls into allocate_resource(), which already falls
back to simple_align_resource() if the alignment function is NULL, which
does the same thing.
So NULL should already work.
