The current buffer check halves the frame rate on non-plus i.MX6Q,
as the IDMAC current buffer pointer is not yet updated when
ipu_plane_atomic_update_pending is called from the EOF irq handler.

Fixes: 70e8a0c7 ("drm/imx: ipuv3-plane: add function to query atomic update status")

History
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.
