[PATCH v1 0/2] Use ACPI_COMPANION macro to obtain acpi_device in cs35l41_hda

[Stefan Binding]

Currently, in cs35l41_hda driver, we use acpi_dev_get_first_match_dev to obtain
the acpi_device used to obtain the properties and gpios.

It is better to use the ACPI_COMPANION macro to do this, since it guarentees
that we get the correct acpi_device for the device.

However, the cs35l41_hda driver uses the serial-multi-instantiate driver to
enumerate, and whilst the ACPI_CONPANION macro works with spi, it does not work
with i2c. This is fixed by setting the fwnode for i2c.
