I don't remember to send the patch relevant to this. Hmm...

Some how I don't receive these mail on my email id.

I have picked up these changes from tizen repository for OdroidXU3.
I have tested with this changes to detect UHS-I micro cd cards.
That's the reason for this email. 


If it's wrong then I will drop it.
