hello sensor_test,

kernel drivers would looking regulators in the device tree,
if there’s regulator_get failed, you should check the definitions in the related device tree.
please double confirm the definitions were all correct.
moreover, you could also disassembler the dtb file into txt file for quick check.
thanks
