From: Marcel Holtmann Date: Fri, 13 Mar 2015 09:11:02 +0000 (-0700) Subject: Bluetooth: Introduce hci_dev_clear_flag helper macro X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a358dc11d80ecaca443aa1fd2fd9d4f3425922e7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Bluetooth: Introduce hci_dev_clear_flag helper macro Instead of manually coding clear_bit on hdev->dev_flags all the time, use hci_dev_clear_flag helper macro.
