sched_can_stop_tick() was using 7 spaces instead of 8 spaces or a 'tab' at the beginning of each line. Which doesn't align with the Coding Guidelines.
Also it removes the *rq variable as it was used at only one place and hence we can directly use this_rq() instead.
Signed-off-by: Viresh Kumar viresh.kumar@linaro.org --- I don't think rq = tihs_rq() has to be done before smp_mb(), in case yes sorry for this patch :(
