Some devices have a bug causing them to not work if they query LE tx power on startup. Thus we add a quirk in order to not query it and default min/max tx power values to HCI_TX_POWER_INVALID.

Sorry for offending you. The thing is that I am inexperienced in the field of submitting patches upstream. v8 shouldn't disappoint you.
If you had done so, you would see the following output in it:
