Bluetooth: Add stubs for synchronous HCI request functionality (5fc16cc4) · Commits · 戴 / test

Prepare hci_request.c to have code for doing synchronous HCI requests, such as LE scanning or advertising changes. The necessary work callbacks will be set up in hci_request_setup() and cleaned up in hci_request_cancel_all(). The former is used when an HCI device get registered, and the latter each time it is powered off (or unregistered). Signed-off-by:
