Thanks. It would be nice if you could send it as a fix for 5.2, it's the
last thing blocking one of my allmodconfig builds. But if you don't
think it qualifies as a fix that's fine too, it can wait.

Sure, no problem. Will do a pull request later.

Hmm, so looking at this more, I was able to produce this config with my
ancient cross-compiler:

CONFIG_EDAC_SUPPORT=y
CONFIG_EDAC=m
CONFIG_EDAC_LEGACY_SYSFS=y
CONFIG_EDAC_MPC85XX=y

Now, mpc85xx_edac is built-in and edac_core.ko is a module
(CONFIG_EDAC=m) and that should not work - i.e., builtin code calling
module functions. But my cross-compiler is happily building this without
complaint. Or maybe I'm missing something.

In any case, I *think* the proper fix should be to do:

config EDAC_MPC85XX
        bool "Freescale MPC83xx / MPC85xx"
        depends on FSL_SOC && EDAC=y

so that you can't even produce the above invalid .config snippet.

Hmmm?
