Fedor Pchelkin ccd87fe7a0 dm zoned: free dmz->ddev array in dmz_put_zoned_devices 
commit 9850ccd5dd88075b2b7fd28d96299d5535f58cc5 upstream.

Commit 4dba12881f ("dm zoned: support arbitrary number of devices")
made the pointers to additional zoned devices to be stored in a
dynamically allocated dmz->ddev array. However, this array is not freed.

Rename dmz_put_zoned_device to dmz_put_zoned_devices and fix it to
free the dmz->ddev array when cleaning up zoned device information.
Remove NULL assignment for all dmz->ddev elements and just free the
dmz->ddev array instead.

Found by Linux Verification Center (linuxtesting.org).

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.
