tick: Remove code duplication in tick_handle_periodic()
tick_handle_periodic() is calling ktime_add() at two places, first before the infinite loop and then at the end of infinite loop. We can rearrange code a bit to fix code duplication here. It looks quite simple and shouldn't break anything, I guess :) Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: linaro-kernel@lists.linaro.org Cc: fweisbec@gmail.com Link: http://lkml.kernel.org/r/be3481e8f3f71df694a4b43623254fc93ca51b59.1395735873.git.viresh.kumar@linaro.org Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
