The drm_format_info_plane_{height,width} functions was implemented using regular division for the plane size calculation, which cause issues [1][2] when used on contexts where the dimensions are misaligned with relation to the subsampling factors. So, replace the regular division by the DIV_ROUND_UP macro. This allows these functions to be used in more drivers, making further work to bring more core presence on them possible.

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.
