On sets actually store the set (closest) format inside ov2680_device.dev, so that it also properly gets returned by get_fmt. This fixes the following problem: 1. App does an VIDIOC_SET_FMT 640x480, calling ov2680_set_fmt() 2. Internal buffers (atomisp_create_pipes_stream()) get allocated at 640x480 size by atomisp_set_fmt() 3. ov2680_get_fmt() gets called later on and returns 1600x1200 since ov2680_device.dev was not updated. So things get configured to stream at 1600x1200, but the internal buffers created during atomisp_create_pipes_stream() do not get updated in size 4. streaming starts, internal buffers overflow and the entire machine freezes eventually due to memory being corrupted Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
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.
