Andy Yan 9a88b6c3c8 drm/rockchip: vop2: Only wait for changed layer cfg done when there is pending cfgdone bits 
[ Upstream commit 7f6721b767 ]

The write of cfgdone bits always done at .atomic_flush.
When userspace makes plane zpos changes of two crtc within one commit,
at the .atomic_begin stage, crtcN will never receive the "layer change
cfg done" event of crtcM because crtcM has not yet written "cfgdone".
So only wait when there is pending cfgdone bits to avoid long timeout.

README 

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.
