The pixel_array control size was calculated incorrectly:
the dimensions were swapped (dims[0] should be the height), and the
values should be the width or height divided by PIXEL_ARRAY_DIV
and rounded up. So don't use roundup, but use DIV_ROUND_UP instead.
This bug is harmless in the sense that nothing will break, except that
it consumes way too much memory for this control.

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 reStructuredText 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.
