From 62aaca0de935221eafe0dfa728d289b588bd768f Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 15 Mar 2017 01:44:49 -0300 Subject: [PATCH] iio: adc: ina2xx: Add OF device ID table The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
