Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
This fixes an integration issue with the regulator device tree bindings
which shook out in -rc. The bindings were overly enthusiatic when
deciding to set a voltage on a regulator and would try to set zero volts
on an unconfigured regulator which isn't supported.

regulator: Set apply_uV only when min and max voltages are defined
