One of our contractors had a look at the patch and had this comment:

One comment/question:
/host/mmci.c in function
"static int __devexit mmci_remove(struct amba_device *dev)" there is code:
         if (regulator_is_enabled(host->vcc))
             regulator_disable(host->vcc);
should "ret = mmc_regulator_set_ocr(mmc, host->vcc, 0);" be added here?
