Under some circumstances gcc will generate an internal call to memcpy(). Alas this bypasses the pre-processor so memcpy is not converted to the kernel's internal memcpy code. The cause is normally a structure assignment, probably this line.
struct seeprom_config *sc = (struct seeprom_config *) scarray;
Try this replacement
struct seeprom_config *sc; memcpy(sc, scarray, sizeof(*sc));
The other possibility I can see is
p->sc = *sc;
try
memcpy(&(p->sc), sc, sizeof(*sc));
