  "Storage fixes for 4.19-rc5

  - Fix for leaking kernel pointer in floppy ioctl (Andy Whitcroft)

  - NVMe pull request from Christoph, and a single ANA log page fix
    (Hannes)

  - Regression fix for libata qd32 support, where we trigger an illegal
    active command transition. This fixes a CD-ROM detection issue that
    was reported, but could also trigger premature completion of the
    internal tag (me)"

  floppy: Do not copy a kernel pointer to user memory in FDGETPRM ioctl
