There's a
/* FIXME - should return -1 */
which can go too.

This breaks at least i82975x_process_error_info() which checks for row
being -1.
And its output gets fed into edac_mc_handle_error() which uses -1 to
denote N/A for some layers.
IOW, so what if it returns -1?
The only thing that needs fixing is removing that FIXME above it.
