Hi Sinan,
Thanks for the update.
Just one small comment below.

Could you arrange the new get_match_data op closer to the other ops that
don't deal with the graphs? Such as device_is_available. As the ops are
dealing generally with fwnodes, I might call this device_get_match_data to
explicitly mention it's for devices.

Same comment about the order here.
