This patch series extend device_get_match_data() to struct bus_type, so that buses like I2C can get matched data. v3->v4: * Documented corner case for device_get_match_data() * Dropped struct i2c_driver parameter from i2c_get_match_data_helper() * Split I2C sysfs handling in seperate patch(patch#3) * Added space after of_device_id for i2c_of_match_device_sysfs() * Added const parameter for struct i2c_client, to prevent overriding it's pointer. * Moved declaration from public i2c.h->i2c-core.h v2->v3: * Added Rb tag from Andy for patch#1. * Extended to support i2c_of_match_device() as suggested by Andy. * Changed i2c_of_match_device_sysfs() as non-static function as it is needed for i2c_device_get_match_data(). * Added a TODO comment to use i2c_verify_client() when it accepts const pointer. * Added multiple returns to make code path for device_get_match_data() faster in i2c_get_match_data(). 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 <lkp@xxxxxxxxx> * 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.
