Greg Kroah-Hartman 1b8b54fc55 memstick: fix memory leak if card device is never registered
commit 4b6d621c9d859ff89e68cebf6178652592676013 upstream.

When calling dev_set_name() memory is allocated for the name for the
struct device.  Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.

Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked.  Fix that leak by manually freeing it right
before the memory for the device is freed.

README

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.
