I have noticed the following error on -next on various ARM64 platforms 
that we have ...

  ERR KERN /dev/mmcblk1: Can't open blockdev

I have bisected this, to see where this was introduced and bisect is 
pointing to this commit. I have not looked any further so far, but 
wanted to see if you had any ideas/suggestions?

Cheers
Jon
