Merge branch 'clockevents/4.13-fixes' of http://git.linaro.org/people/daniel.lezcano/linux into timers/urgent

Pull clockevents fixes from Daniel Lezcano:

" - Fix error check against IS_ERR() instead of NULL for the timer-of code (Dan Carpenter)
  - Fix infinite recusion with ftrace for the ARM architected timer (Ding Tianhong)
  - Fix the error code return in the em_sti's probe function (Gustavo A. R.  Silva)
  - Fix Kconfig dependency for the pistachio driver (Matt Redfearn)
  - Fix mem frame loop initialization for the ARM architected timer (Matthias Kaehlcke)"
