Hi, This new patch series changes the approach to enabling the no-1.8V quirk. We determined that not having the DSM method might not be a good enough signal for the board/eMMC not supporting 1.8V. It now uses a DMI quirk; I've also added another machine which benefited from the previous patch, but for which the issue is harder to reproduce. I've kept the previous cleanup of the voltage_switch callback in an optional third patch, but it does not enable any quirk.
