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));
