Sorry I had my wrap length configured to 80 but just changed to 74 now.

Indeed. I'll change mmc_regulator_get_ocrmask() in MMC core then to use
regulator_can_change_voltage() to detect if the regulator is a fixed one
and call regulator_get_voltage() instead of list_voltage() in that case.

Do you agree that this is the correct solution?
