From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
commit 95e0cf3caeb11e1b0398c747b5cfa12828263824 upstream.
The I2C host driver for SynQuacer fails to populate the of_node and ACPI companion fields of the struct i2c_adapter it instantiates, resulting in enumeration of the subordinate I2C bus to fail.
