[x] Bug report

Environment

• Python version: 3.6
• NetBox version: at least 2.3.3 to e82bf66

Description

• Create or update a device type through the API by setting subdevice_role to null.
• You should get a 400 error, containing this message: {"subdevice_role":["This field may not be null."]}

I tried to force the attribute as non required in its serializer, but it apparently didn't fix the issue.

Thanks!

I debugged a bit, and it seems that allow_null is set to False for the ChoiceFieldSerializer here. Forcing it to True fixes the issue.

Thanks a lot!
