From bb87672562f871edd7a220222dd2480a87294580 Mon Sep 17 00:00:00 2001 From: Brian Gix Date: Thu, 21 Jul 2022 16:22:24 -0700 Subject: Bluetooth: Remove update_scan hci_request dependancy This removes the remaining calls to HCI_OP_WRITE_SCAN_ENABLE from hci_request call chains, and converts them to hci_sync calls.
