Fix tmio MMC_POWER_UP invocation which had been broken in linux-2.6.39-rc1. In tmio_mmc_set_ios() an affirmative test for ios->clock == 0 executes the MMC_POWER_OFF block regardless of ios->power_mode. Because mmc_power_up() invokes MMC_POWER_UP before setting ios->clock, tmio_mmc_set_ios() turns the MMC power off instead of on.
