Subject: [PATCH 0/3] regulator: gpio-regulator: Fixes for problems that turned up with 3.5-rc1

During the porting of my machine to 3.5-rc1 some glitches in the
gpio-regulator from different changes popped up.

This series fixes these.

While doing this, I noticed a possible uninitialized use of "selector" in
_regulator_do_set_voltage, where I'm not sure what the correct fix would be.

To summarize, before
	if (rdev->desc->ops->list_voltage)
		best_val = rdev->desc->ops->list_voltage(rdev, selector);
	else
		best_val = -1;

selector is set in the set_voltage callback or if the new map_voltage returns
a non-error value. If it returns an error value or the else clause is reached
selector is used uninitialized in the list_voltage and set_voltage_time_sel
call.

As written above, I'm not sure what the correct fix would be here.

Heiko Stuebner (3):
  regulator: gpio-regulator: do not pass drvdata pointer as reference
  regulator: gpio-regulator: Fix finding of smallest value
  regulator: gpio-regulator: populate selector from set_voltage
