[PATCH 5.4 15/34] drivers: i2c: thunderx: Allow driver to work with ACPI defined TWSI controllers

[Greg Kroah-Hartman]

From: Piyush Malgujar <pmalgujar@xxxxxxxxxxx>

[ Upstream commit 03a35bc856ddc09f2cc1f4701adecfbf3b464cb3 ]

Due to i2c->adap.dev.fwnode not being set, ACPI_COMPANION() wasn't properly
found for TWSI controllers.
