X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=348409a267e441c46345f325db37e9824fcf675e;p=openwrt%2Fstaging%2Fblogic.git

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.
