Well, I am ok with this but this info is very useful, what if PMIC
failed to actually set the voltage? may be because of some PMIC driver
bug or i2c driver bug? Ofcourse this can be found by turning MMC_DEBUG
ON, but is that worth in this case. Or is there a way to print that,
this failure is because of a regulator re-try?
your thoughts?
