[ Upstream commit 8f2e452730d2bcd59fe05246f0e19a4c52e0012d ]
The media_device_usb_allocate() function returns error pointers when
it's enabled and something goes wrong. It can return NULL as well, but
only if CONFIG_MEDIA_CONTROLLER is disabled so that doesn't apply here.
Fixes: 812658d88d26 ("media: change au0828 to use Media Device Allocator API")

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.
