From: Javier Martinez Canillas javier@osg.samsung.com
[ Upstream commit cf5cd9d4480a87da78768718cac194a71079b5cb ]
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:<device>.
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.
The compatible strings don't have a vendor prefix because that's how it's used currently, and changing this will be a Device Tree ABI break.
