hwmon: (max31785) 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:<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. Before this patch: $ modinfo drivers/hwmon/pmbus/max31785.ko | grep alias alias: i2c:max31785a alias: i2c:max31785 After this patch: $ modinfo drivers/hwmon/pmbus/max31785.ko | grep alias alias: i2c:max31785a alias: i2c:max31785 alias: of:N*T*Cmaxim,max31785aC* alias: of:N*T*Cmaxim,max31785a alias: of:N*T*Cmaxim,max31785C* alias: of:N*T*Cmaxim,max31785 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
