From 348409a267e441c46345f325db37e9824fcf675e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 21 Dec 2012 17:57:12 -0800 Subject: [PATCH] usb: gadget: 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.
