Subject[PATCH v2 0/3] i2c: introduce devm_i2c_new_dummy and use it in at24 driver
Date
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.

Changes in v2:
- add change to i2c core to make a version of i2c_new_device
available which returns an ERR_PTR instead of NULL in error case
- few minor improvements

Heiner Kallweit (3):
i2c: core: improve return value handling of i2c_new_device and i2c_new_dummy
i2c: core: add device-managed version of i2c_new_dummy
eeprom: at24: switch to device-managed version of i2c_new_dummy
