Your regulator probably _shouldn't_ be "always on" (it prevents power cycling the SD card) but right now it's good that it is... If any board has a "vmmc" that is not listed as always on then it would regress with the first two patches applied (and without the 3rd), but there are none that I personally know of that do. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
