      Bluetooth: btusb: fix memory leak in btusb_mtk_submit_wmt_recv_urb() · 60c6a63a
      Mark-YW.Chen authored
      Driver should free `usb->setup_packet` to avoid the leak.

      hci_alloc_dev() do not init the device's flag. And hci_free_dev()
      using put_device() to free the memory allocated for this device,
      but it calls just put_device(dev) only in case of HCI_UNREGISTER
      flag is set, So any error handing before hci_register_dev() success
      will cause memory leak.
      
      To avoid this behaviour we can using kfree() to release dev before
      hci_register_dev() success.

      Bluetooth: btintel: Fix bdaddress comparison with garbage value · 89350531
      Kiran K authored
      Intel Read Verision(TLV) data is parsed into a local structure variable
      and it contains a field for bd address. Bd address is returned only in
      bootloader mode and hence bd address in TLV structure needs to be validated
      only if controller is present in boot loader mode.

      Bluetooth: Fix handling of SUSPEND_DISCONNECTING · 83775456
      Luiz Augusto von Dentz authored
      When SUSPEND_DISCONNECTING bit is set that means Disconnect is pending
      but the code was evaluating if the list is empty before calling
      hci_conn_del which does the actual cleanup and remove the connection
      from the list thus the bit is never cleared causing the suspend
      procedure to always timeout when there are connections to be
      disconnected:
