You're right, it's not. A forward declaration of struct regulator would
suffice.

Hm, actually, I don't think so. sh_mmcif_set_power() is called as a part
of the driver's .set_ios() method. The core has to call that method
regardless whether MMC_CAP_POWER_OFF_CARD is set or not. Only inside that
method we can decide, that a part of its functionality (power on / off) is
unavailable.
