* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6: (45 commits)
  regulator: missing index in PTR_ERR() in isl6271a_probe()
  regulator: Assign return value of mc13xxx_reg_rmw to ret
  regulator: Add initial per-regulator debugfs support
  regulator: Make regulator_has_full_constraints a bool
  regulator: Clean up logging a bit
  regulator: Optimise out noop voltage changes
  regulator: Add API to re-apply voltage to hardware
  regulator: Staticise non-exported functions in mc13892
  regulator: Only notify voltage changes when they succeed
  regulator: Provide a selector based set_voltage_sel() operation
  regulator: Factor out voltage set operation into a separate function
  regulator: Convert WM8994 to use get_voltage_sel()
  regulator: Convert WM835x to use get_voltage_sel()
  regulator: Allow modular build of mc13xxx-core
  regulator: support PMIC mc13892
  make mc13783 regulator code generic
  Change the register name definitions for mc13783
  mach-ux500: Updated and connected ab8500 regulator board configuration
