Video driver maintains an internal context for the output buffer size. During S_fmt() on capture plane, the output buffer size is not updated in driver context. As a result, during buf_prepare(), the size of the vb2_plane and internal size of the buffer, as maintained by the driver, does not match. This leads to buf_prepare() failure. Update the instance context for the output buffer size during s_fmt().

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.
