RFC v1->v2: * Replaced "Signed-off-by"->"Suggested-by" tag for Dmitry. * Documented device_get_match_data(). * Added multiple returns to make code path for generic fwnode-based lookup faster. * Fixed build warnings reported by kernel test robot * Added const qualifier to return type and parameter struct i2c_driver in i2c_get_match_data_helper(). * Added const qualifier to struct i2c_driver in i2c_get_match_data() * Dropped driver variable from i2c_device_get_match_data() * Replaced to_i2c_client with logic for assigning verify_client as it returns non const pointer.
