Bluetooth: Add callback to create proper cmd_complete events
We've got a couple of generic scenarios where all pending mgmt commands are processed and responses are sent to them. These scenarios are powering off the adapter and removing the adapter. So far the code has been generating cmd_status responses with NOT_POWERED and INVALID_INDEX resposes respectively, but this violates the mgmt specification for commands that should always generate a cmd_complete. This patch adds support for specifying a callback for the pending_cmd context that each command handler can use for command-specific cmd_complete event generation. The actual per-command event generators will come in subsequent patches. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
