* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6:
  regulator: Fix default constraints for fixed voltage regulators
  regulator/bq24022: fix bug in is_enabled function
  regulator/virtual: fix strings compare predicates
  regulator core: fix double-free in regulator_register() error path
  drivers/regulator: fix when type is different from REGULATOR_VOLTAGE or REGULATOR_CURRENT
  unreachable code in drms_uA_update()
  regulator: fix header file missing kernel-doc
