From 47a0925ee4bd2689f0aef4dbd67dd46442fe1ca2 Mon Sep 17 00:00:00 2001 From: Maud Spierings Date: Thu, 30 Oct 2025 07:35:38 +0100 Subject: [PATCH] regulator: bd718x7: Fix voltages scaled by resistor divider 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.
