From: Ross Burton <ross.burton(a)intel.com&gt; Instead of using min_power, which has reports of data corruption, use med_power_with_dipm (Device Interface Power Management) available since 4.15. This has the same behaviour as the Windows IRST driver so both power usage and stability should be improved. See https://lore.kernel.org/patchwork/patch/830838/ for more context.
