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/max1586: fix V3 gain calculation integer overflow
regulator/max1586: support increased V3 voltage range
regulator: lp3971 - fix driver link error when built-in.
LP3971 PMIC regulator driver (updated and combined version)
regulator: remove driver_data direct access of struct device
regulator: Set MODULE_ALIAS for regulator drivers
regulator: Support list_voltage for fixed voltage regulator
regulator: Move regulator drivers to subsys_initcall()
regulator: build fix for powerpc - renamed show_state
regulator: add userspace-consumer driver
