From: Luiz Augusto von Dentz Date: Fri, 12 Nov 2021 00:48:43 +0000 (-0800) Subject: Bluetooth: hci_sync: Convert MGMT_OP_SET_CONNECTABLE to use cmd_sync X-Git-Tag: baikal/aarch64/sdk6.1~4966^2~428^2~4 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=52bdfdb358d121bf2512c52bbd5b2805d32d716e;p=kernel.git Bluetooth: hci_sync: Convert MGMT_OP_SET_CONNECTABLE to use cmd_sync This makes MGMT_OP_SET_CONNEABLE use hci_cmd_sync_queue instead of use a dedicated connetable_update work.
