Bluetooth: Fix issue with Actions Semi ATS2851 based devices
Browse files Browse the repository at this point in the history
Their devices claim to support the erroneous data reporting, but don't
actually support the required commands. So blacklist them and add a
quirk.

  < HCI Command: Read Default Erroneous Data Reporting (0x03|0x005a) plen 0
  > HCI Event: Command Status (0x0f) plen 4
        Read Default Erroneous Data Reporting (0x03|0x005a) ncmd 1
          Status: Unknown HCI Command (0x01)
