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: Add MODULE_DEVICE_TABLE to max8997 and max8998 regulator: fix tps6524x section mismatch regulator: Remove more wm831x-specific IRQ operations regulator: add ab8500 enable and raise time delays regulator: provide consumer interface for fall/rise time regulator: add set_voltage_time_sel infrastructure regulator: initialization for ab8500 regulators regulator: add support for USB voltage regulator regulator: switch the ab3100 to use enable_time() Regulator: add suspend-finish API for regulator core. regulator: fix typo in Kconfig regulator: Convert WM831x regulators to genirq regulator: If we fail when setting up a supply say which supply
