Pull clocksource/event driver updates from Thomas Gleixner:

 - Remove redundant dev_err() and dev_err_probe() invocations in various
   drivers

 - Handle SWAP_IO_SPACE correctly in the rtl-otto driver

 - Make the Samsumg PWM timer driver PREEMPT_RT compatible

 - Ensure that the SUN4I timer is programmed with a delta larger than
   zero as a zero delta causes the the timer to be disabled
