| Subject: i2c: synquacer: fix enumeration of slave devices |
| |
| 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. |
| |
| Fixes: 0d676a6c4390 ("i2c: add support for Socionext SynQuacer I2C controller") |
