From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tejun Heo Subject: [PATCH 17/25] wm97xx: don't use [delayed_]work_pending() Date: Fri, 21 Dec 2012 17:57:07 -0800 Message-ID: <1356141435-17340-18-git-send-email-tj@kernel.org> References: <1356141435-17340-1-git-send-email-tj@kernel.org> Return-path: In-Reply-To: <1356141435-17340-1-git-send-email-tj@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: Tejun Heo , Mark Brown , Liam Girdwood , linux-input@vger.kernel.org, Dmitry Torokhov List-Id: linux-input@vger.kernel.org There's no need to test whether a (delayed) work item in pending before queueing, flushing or cancelling it. Most uses are unnecessary and quite a few of them are buggy. Remove unnecessary pending tests from wm97xx. Instead of testing work_pending(), use the return value of queue_work() to decide whether to disable IRQ or not. Only compile tested.

I can take it through the workqueue tree if necessary.
