platform_device_unregister() should only be called when a respective platform_device_register() is called. However the floppy driver currently allows failures when registring a drive and a bail out could easily cause an invalid call to platform_device_unregister() where it was not intended. Fix this by adding a bool to keep track of when the platform device was registered for a drive. This does not fix any known panic / bug. This issue was found through code inspection while preparing the driver to use the up and coming support for device_add_disk() error handling. From what I can tell from code inspection, chances of this ever happening should be insanely small, perhaps OOM.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
