[PATCH] regulator: qcom_spmi: Always return a selector when asked

[PATCH] regulator: qcom_spmi: Always return a selector when asked

[Stephen Boyd]

I had a thinko in spmi_regulator_select_voltage_same_range() when
converting it to return selectors via the function's return value
instead of by modifying a pointer argument. I only tested
multi-range regulators so this passed through testing. Fix it by
returning the selector here.

Applied "regulator: qcom_spmi: Always return a selector when asked" to the regulator tree

[Mark Brown]

The patch

   regulator: qcom_spmi: Always return a selector when asked

has been applied to the regulator tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
