i2c: synquacer: fix enumeration of slave devices
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. Fixes: 0d676a6c4390 ("i2c: add support for Socionext SynQuacer I2C controller") Cc: <stable@vger.kernel.org> # v4.19+ Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
