We have several drivers that have a core and separate i2c and spi
wrappers, see e.g.
$ git grep -w ltc2947_of_match
drivers/hwmon/ltc2947-core.c:const struct of_device_id ltc2947_of_match[] = {
drivers/hwmon/ltc2947-core.c:EXPORT_SYMBOL_GPL(ltc2947_of_match);
drivers/hwmon/ltc2947-core.c:MODULE_DEVICE_TABLE(of, ltc2947_of_match);
drivers/hwmon/ltc2947-i2c.c: .of_match_table = ltc2947_of_match,
drivers/hwmon/ltc2947-spi.c: .of_match_table = ltc2947_of_match,
drivers/hwmon/ltc2947.h:extern const struct of_device_id ltc2947_of_match[];
Are they all broken?
