Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6 

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6:
  regulator: Add MODULE_DEVICE_TABLE to max8997 and max8998
  regulator: fix tps6524x section mismatch
  regulator: Remove more wm831x-specific IRQ operations
  regulator: add ab8500 enable and raise time delays
  regulator: provide consumer interface for fall/rise time
  regulator: add set_voltage_time_sel infrastructure
  regulator: initialization for ab8500 regulators
  regulator: add support for USB voltage regulator
  regulator: switch the ab3100 to use enable_time()
  Regulator: add suspend-finish API for regulator core.
  regulator: fix typo in Kconfig
  regulator: Convert WM831x regulators to genirq
  regulator: If we fail when setting up a supply say which supply
