Patch-mainline: Never, SLE12-SP2/3 only
References: bsc#1042536

An error message like below is a common pattern found on many laptops
and actually it's a harmless notification:
  mmc0: Unknown controller version (3). You may experience problems.

For a better mental health of users, let's downgrade the kernel error
level for this message.
