These patches are mentioned in an email thread by Adrian Hunter (one of the primary maintainers of the MMC module in the kernel).
I will do some check for these patches.
Before I confirm which patches are needed, I set this issue incomplete temporarily.
This issue was reported also existed in Ubuntu 15.10, however I tested the mainline kernel v4.5 and it works fine.

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete
