From: wanghaibin Date: Thu, 7 Jan 2016 12:38:59 +0000 (+0800) Subject: workqueue: simplify the apply_workqueue_attrs_locked() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6201171e3b2c02992e62448636631a0dfe4e9d20;p=openwrt%2Fstaging%2Fblogic.git workqueue: simplify the apply_workqueue_attrs_locked() If the apply_wqattrs_prepare() returns NULL, it has already cleaned up the related resources, so it can return directly and avoid calling the clean up function again. This doesn't introduce any functional changes.
