Unfortunately that won't help the OP at all: he has the floppy working
correctly under 4.9, but his aim was to be able to use the floppy
drive under 5.2.1, and your instructions won't work because:

    * MAKEDEV is gone from 5.x, which now uses devfs stuff instead to
    dynamically create all the device nodes corresponding to the
    available hardware.

    * fdc0 wasn't being probed successfully on the OP's machine under
    5.x, so the kernel has no way to access the floppy drive.
    Unfortunately that is a bug in the system, for which there appears
    to be no satisfactory fix yet available.  See


A work-around is to disable ACPI (as described in that PR), which will
prevent you automatically controlling the power on your system and
various other similar things, but should let you access the floppy
