That is not how you migrate a driver from hwmon_device_register() to hwmon_device_register_with_info().
You are expected to also move the sysfs-centric attribute handling to struct hwmon_chip_info.

Thanks,

- Please do not top post
- Please resend your patch if you make significant changes to it
- Please do not send patches as attachments (use git send-email for example)
- The attached patch still does not use struct hwmon_chip_info

Thanks,
Armin Wolf
