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

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6:
  regulator: return set_mode is same mode is requested
  Regulators: ab3100/bq24022: add a missing .owner field in regulator_desc
  twl6030: regulator: Remove vsel tables and use formula for calculation
  mc13783-regulator: fix vaild voltage range checking for mc13783_fixed_regulator_set_voltage
  regulator: use voltage number array in 88pm860x
  regulator: make 88pm860x sharing one driver structure
  regulator: simplify regulator_register() error handling
  regulator: fix unset_regulator_supplies() to remove all matches
  regulator: prevent registration of matching regulator consumer supplies
  regulator: Allow regulator-regulator supplies to be specified by name
