commit751281c555upstream. When FB_DAMAGE_CLIPS are provided in a non-MPO scenario, the loop does not use the counter i. This causes the fill_dc_dity_rect() to always fill dirty_rects[0], causing graphical artifacts when a damage clip aware DRM client sends more than 1 damage clip. Instead, use the flip_addrs->dirty_rect_count which is incremented by fill_dc_dirty_rect() on a successful fill.

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.
