Subject: net/usb/drivers: Remove useless hrtimer_active check
X-Git-Tag: v4.19~747^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2aee167c3675b088c86f648f834e793a0085e04d;p=platform%2Fkernel%2Flinux-rpi3.git

net/usb/drivers: Remove useless hrtimer_active check

The code does:

 if (hrtimer_active(&t))
    hrtimer_cancel(&t);

However, hrtimer_cancel() checks if the timer is active, so the
test above is pointless.
