Subject[PATCH 3.18 12/69] usb: phy: isp1301: Add OF device ID table
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Javier Martinez Canillas <javier@osg.samsung.com>


[ Upstream commit fd567653bdb908009b650f079bfd4b63169e2ac4 ]

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.
