[ Upstream commit 2b8358a951b1e2a534a54924cd8245e58a1c5fb8 ]
The mpc85xx EDAC driver can be configured as a module but then fails to build because it uses two unexported symbols:
ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined! ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined!
We don't want to export those symbols just for this driver, so make the driver only configurable as a built-in.
This seems to have been broken since at least
c92132f59806 ("edac/85xx: Add PCIe error interrupt edac support")
(Nov 2013).
[ bp: make it depend on EDAC=y so that the EDAC core doesn't get built as a module. ]
