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 Maxim 1586 regulator driver
