Ricardo Ribalda a03fb1e8a1 media: staging/intel-ipu3: Fix set_fmt error handling
commit ad91849996f9dd79741a961fd03585a683b08356 upstream.

If there in an error during a set_fmt, do not overwrite the previous
sizes with the invalid config.

Without this patch, v4l2-compliance ends up allocating 4GiB of RAM and
causing the following OOPs

[   38.662975] ipu3-imgu 0000:00:05.0: swiotlb buffer is full (sz: 4096 bytes)
[   38.662980] DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:00:05.0
[   38.663010] general protection fault: 0000 [#1] PREEMPT SMP

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.
