Re: [PATCH v5] Bluetooth: Keep MSFT ext info throughout a hci_dev's life cycle

Hi Manish,

This moves msft_do_close() from hci_dev_do_close() to
hci_unregister_dev() to avoid clearing MSFT extension info. This also
re-reads MSFT info upon every msft_do_open() even if MSFT extension has
been initialized.

The following test steps were performed.
(1) boot the test device and verify the MSFT support debug log in syslog
(2) restart bluetoothd and verify msft_do_close() doesn't get invoked
   and msft_do_open re-reads the MSFT support.

so tell me how this can be correct. The msft_do_close does cleanup of instances. If we close the device via power down I would expect that these instances are cleared. Do they survive a HCI Reset command?

I think it would be better to introduce an additional msft_register / msft_unregister pair if this needs to be more complex.

Regards

Marcel
