Subject: [PATCH v2 2/3] Bluetooth: Remove update_scan hci_request dependancy
Date: Thu, 21 Jul 2022 16:22:24 -0700 [thread overview]
Message-ID: <20220721232225.624426-3-brian.gix@intel.com> (raw)
In-Reply-To: <20220721232225.624426-1-brian.gix@intel.com>
This removes the remaining calls to HCI_OP_WRITE_SCAN_ENABLE from
hci_request call chains, and converts them to hci_sync calls.
Signed-off-by: Brian Gix <brian.gix@intel.com>
