Bluetooth: Read Verbose Config Version Info for Broadcom devices
The Broadcom devices expose their chip id via Read Verbose Config Version Info command. While this information is not used at the moment, it might be useful for debugging purposes and so read it before patching the firmware. This makes it show up in dmesg and HCI traces taken for the system. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
