As per the SMBIOS spec, this should be the name of the slot as printed on the mainboard. If memory serves right, the slots are `SO-DIMM A0` and `SO-DIMM B0`. So, this should be:

snprintf(dev_loc, sizeof(dev_loc), "SO-DIMM %c%u", 'A' + mc, mm);

If you don't like the `'A' + mc` part, feel free to change it. But this would be the idea.

nit: use `%u` because unsigned. Also, maaaybe separate the numbers with hyphens or the like for clarity?
