Pull initramfs fix from Stafford Horne:
 "This is a fix for an issue that has caused 4.11 to not boot on
  OpenRISC. I should have caught this during the 4.11 cycle but I had
  been busy on testing some other series of patches.

  I would have considered pushing it though a different path but Al Viro
  suggested submitting directly to you.

  Also, its just one as I havent really got anything else ready on my
  queue for 4.12.

  Summary:

   - Ensure fput() flush is done even for builtin initramfs"
