Signed-off-by: Biju Das --- v2->v3: * Added .name field to MCP4018_ID_TABLE macro * Replaced MCP4018_ID_TABLE(name, cfg)->MCP4018_ID_TABLE(_name, cfg) v1->v2: * Added similar I2C and DT-based matching table. * Fixed typo i2c_get_match_data(dev)->i2c_get_match_data(client). * Dropped error check as all tables have data pointers.
