commit9850ccd5ddupstream. Commit4dba12881f("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).

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.
