Laurent Pinchart d6e5ba2516 media: uvcvideo: Fix double free in error path
commit c6ef3a7fa97ec823a1e1af9085cf13db9f7b3bac upstream.

If the uvc_status_init() function fails to allocate the int_urb, it will
free the dev->status pointer but doesn't reset the pointer to NULL. This
results in the kfree() call in uvc_status_cleanup() trying to
double-free the memory. Fix it by resetting the dev->status pointer to
NULL after freeing it.

Fixes: a31a405547 ("V4L/DVB:usbvideo:don't use part of buffer for USB transfer #4")

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.
