Date: Fri, 21 Dec 2012 17:57:12 -0800 From: Tejun Heo <tj@...nel.org> To: linux-kernel@...r.kernel.org Cc: Tejun Heo <tj@...nel.org>, Andrew Victor <linux@...im.org.za>, Nicolas Ferre <nicolas.ferre@...el.com>, Jean-Christophe Plagniol-Villard <plagnioj@...osoft.com>, Felipe Balbi <balbi@...com>, linux-usb@...r.kernel.org Subject: [PATCH 22/25] usb/at91_udc: don't use [delayed_]work_pending() 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 at91_udc. Only compile tested.
