Merge tag 'regulator-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"Aside from a fix for a spurious warning (which caused more problems
than it fixed in the fixing really) this is all driver updates,
including new drivers for Dialog PV88060/90 and TI LM363x and TPS65086
devices. The qcom_smd driver has had PM8916 and PMA8084 support
added"
