[alsa-devel] [PATCH 4/8] drm: encoder_slave: Don't use i2c_client->driver

[Lars-Peter Clausen]

The 'driver' field of the i2c_client struct is redundant and is going to be
removed. The results of the expressions 'client->driver.driver->field' and
'client->dev.driver->field' are identical, so replace all occurrences of the
former with the later. To get direct access to the i2c_driver struct use
'to_i2c_driver(client->dev.driver)'.
