Thanks, looks good. But looking at this driver, mv64x60_mc_err_probe()
and mv64x60_sram_err_probe() have the same problem too. Can you address them
with your patch too pls?

Also, if you feel like fixing more stuff in this driver, it doesn't use
the edac_printk() infrastructure but naked printk() calls. It could be
converted to it.

Thx.
