parenti2c: core: improve return value handling of i2c_new_device and i2c_new_dummy (diff)
i2c: core: add device-managed version of i2c_new_dummy
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. Note the changed error case return value type: i2c_new_dummy returns NULL whilst devm_i2c_new_dummy_device returns an ERR_PTR.
