This commit updates the dm_force_atomic_commit function to replace the usage of PTR_ERR_OR_ZERO with IS_ERR for checking error states after retrieving the Connector (drm_atomic_get_connector_state), CRTC (drm_atomic_get_crtc_state), and Plane (drm_atomic_get_plane_state) states. The function utilized PTR_ERR_OR_ZERO for error checking. However, this approach is inappropriate in this context because the respective functions do not return NULL; they return pointers that encode errors. This change ensures that error pointers are properly checked using IS_ERR before attempting to dereference.

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.
