Axel Lin a9bbb453b5 regulator: vctrl: Fix out of bounds array access for vctrl->vtable 
Current code only allocates rdesc->n_voltages entries for vctrl->vtable.
Thus use rdesc->n_voltages instead of n_voltages in the for loop.

While at it, also switch to use devm_kcalloc instead of devm_kmalloc_array
+ __GFP_ZERO flag and fix the argument order.

Matthias Kaehlcke 9dee7a72d0 regulator: Add driver for voltage controlled regulators 
The output voltage of a voltage controlled regulator can be controlled
through the voltage of another regulator. The current version of this
driver assumes that the output voltage is a linear function of the control
voltage.
