[PATCH] sis190: remove hardcoded constants.
Replace hardcoded constants by enumerated values in sis190_read_eeprom The names of the enumerated values have been extracted from SiS'official driver (v1.00.00 published on 2005/07/11). Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
