From a69d89272698d1c31ccb78348562af6461cf1eb7 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 13 Mar 2015 02:11:05 -0700 Subject: [PATCH] Bluetooth: Introduce hci_dev_test_and_clear_flag helper macro Instead of manually coding test_and_clear_bit on hdev->dev_flags all the time, use hci_dev_test_and_clear_flag helper macro.
