[PATCH v2 2/2] hwmon: (lm87) Add OF device ID table

From: Javier Martinez Canillas
Date: Wed Apr 12 2017 - 20:22:16 EST


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.

Best regards,

Changes in v2:
- Use the correct driver in subject line.
- Keep OF device ID table sorted in the same order than I2C device ID table.
