If anyone has any objections, please let me know. ------------------ From: Imre Deak [ Upstream commit d7fa5754e83cd36c4327eb2d806064e598a72ff6 ] The BIOS can leave the AUX power well enabled on an output, even if this isn't required (on platforms where the AUX power is only needed for an AUX access). This was observed at least on PTL. To avoid the WARN which would be triggered by this during the HW readout, convert the WARN to a debug message.
