From: Marcel Holtmann Date: Fri, 13 Mar 2015 09:11:06 +0000 (-0700) Subject: Bluetooth: Introduce hci_dev_test_and_set_flag helper macro X-Git-Tag: Ubuntu-5.2.0-15.16~11548^2~244^2~12 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=238be788fcb75870661ec165dc90f2a2674e7fcb;p=mirror_ubuntu-eoan-kernel.git Bluetooth: Introduce hci_dev_test_and_set_flag helper macro Instead of manually coding test_and_set_bit on hdev->dev_flags all the time, use hci_dev_test_and_set_flag helper macro.
