  Removed drivers:
   - ab3100
   - coh901331
   - tx4939
   - sirfsoc

  Drivers:
   - use rtc_lock and rtc_unlock instead of opencoding
   - constify all struct rtc_class_ops
   - quiet maybe-unused variable warning
   - replace spin_lock_irqsave with spin_lock in hard IRQ
   - pcf2127: disable Power-On Reset Override and run OTP refresh"
