-/**
- * drm_i2c_encoder_init - Initialize an I2C slave encoder
- * @dev:	DRM device.
- * @encoder:    Encoder to be attached to the I2C device. You aren't
- *		required to have called drm_encoder_init() before.
- * @adap:	I2C adapter that will be used to communicate with
- *		the device.
- * @info:	Information that will be used to create the I2C device.
- *		Required fields are @addr and @type.
- *
- * Create an I2C device on the specified bus (the module containing its
- * driver is transparently loaded) and attach it to the specified
- * &drm_encoder_slave. The @slave_funcs field will be initialized with
- * the hooks provided by the slave driver.
- *
- * If @info.platform_data is non-NULL it will be used as the initial
- * slave config.
- *
- * Returns 0 on success or a negative errno on failure, in particular,
- * -ENODEV is returned when no matching driver is found.
