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: (27 commits)
regulator: wm831x_reg_read() failure unnoticed in wm831x_aldo_get_mode()
twl-regulator: Fix reg_disable functionality for 4030 and 6030
twl-regulator: Add turnon delay to reg_enable
twl-regulator: Restore REMAP configuration in regulator probe
twl-regulator: Add turnon-delay and REMAP config to twlreg_info struct
twl-regulator: Define critical regulators as always_on
twl-regulator: Add all twl4030 regulators to twlreg_info
regulator: mc13783-regulator: correct the probing time.
regulator: Fix unbalanced disables/enables in regulator_bulk_{enable,disable} error path
regulator: core.c: Small coding style cleanup (indentation fixup)
drivers/regulator: use PTR_ERR to get error code
regulator: consumer.h - fix build when consumer.h is #included first.
regulator/mc13783: various cleanups
regulator/mc13783: rename source file to match other drivers
Fix some AB3100 regulator issues
regulator: keep index within bounds in da9034_get_ldo12_voltage()
regulator: Ensure val is initialised in 88pm8607 choose_voltage()
regulator: Remove duplicate consts from ab3100
regulator: Handle regulators without suspend mode configuration
regulator: Factor out regulator name pretty printing
