Commit0650a91499("media: mtk-vcodec: Correct return type for mem2mem buffer helpers") fixed the return types for mem2mem buffer helper functions by changing a few local variables from vb2_buffer to vb2_v4l2_buffer. However, it left a few accesses to vb2_buffer::planes as-is, accidentally turning them into accesses to vb2_v4l2_buffer::planes and resulting in values being read from/written to the wrong place. Fix this by inserting vb2_buf into these accesses so they mimic their original behavior.

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.
