Hi Andrei and Edoardo,

Thanks for the reply.

Although this is HWE, we do accept changes to enable new hardware in
some cases:
https://ubuntu.com/project/docs/SRU/reference/requirements/#other-safe-cases

Since the driver doesn’t conflict with others and is already in
resolute, could you reconsider whether we can treat this as one of those
exceptions?

Thanks,
Jesse
