I am using git format-patch only. I think the name of series is changed causing the trouble.

Yes, these are name of pins.

Below is the Pin Description from NT36672E Datasheet:

vddi - Power supply to the I/O.
avdd - Positive input analog power for driver IC use.
avee - Negative input analog power for driver IC use.

I could not find datasheet of NT36672A online to compare the names.

Thanks,
