regulator: bd718x7: Fix voltages scaled by resistor divider

47a0925e · Maud Spierings <[email protected]> · 2025-10-30 07:35:38 +01:00

The .min_sel and .max_sel fields remained uninitialized in the new
linear_range, causing an error further down the line. Copy the old
values of these fields to the new one as they represent the range of
register values, which does not change.
