      Bluetooth: Fix reporting incorrect EIR in device found mgmt event · 6818375e
      Szymon Janc authored
      Some remote devices (ie Gigaset G-Tag) misbehave with ADV data length.
      This can lead to incorrect EIR format in device found event when
      ADV_DATA and SCAN_RSP are merged (terminator field before SCAN_RSP
      part).
      
      Fix this by inspecting ADV_DATA and correct its length if terminator
      is found.

      Note "Data length: 30" in ADV_DATA which results in 9 extra zero bytes
      after Battery Service UUID. Terminator field present in the middle of
      EIR in Device Found event resulted in userspace stop parsing EIR and
      skipping device name.
