Added p_s32 and p_s64 pointers to the union in struct v4l2_ext_control to simplify INTEGER and INTEGER64 control array support. Internally the control framework handles such arrays just fine, but userspace is missing corresponding pointers to access array elements of these types. The internal union v4l2_ctrl_ptr which the control framework uses already has these types, they just were never added to the public API. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
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.
