i2c_new_dummy is typically called from the probe function of the
driver for the primary i2c client. It requires calls to
i2c_unregister_device in the error path of the probe function and
in the remove function.
This can be simplified by introducing a device-managed version.

Make at24 driver the first user of the new function.

Patch 1 has been submitted and reviewed some time ago, however it
was waiting for a first user until now.

Heiner Kallweit (2):
  i2c: core: add device-managed version of i2c_new_dummy
  eeprom: at24: switch to device-managed version of i2c_new_dummy
