vim2m_device_release() will be called by video_unregister_device() to release
various objects.
There are two double-free issue,
1. dev->m2m_dev will be freed twice in error_m2m path/vim2m_device_release
2. the error_v4l2 and error_free path in vim2m_probe() will release
same objects, since vim2m_device_release has done.
Fixes: ea6c7e34f3 ("media: vim2m: replace devm_kzalloc by kzalloc")

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.
