The original logic is ok for primary display, but will not find out
component for external display.
For example, plane->index is 6 for external display, but there are only
2 layer nr in external display, and this condition will never happen:
if (plane->index < (count + mtk_ddp_comp_layer_nr(comp)))
Fix this by using the offset of the plane to mtk_crtc->planes as index,
instead of plane->index.

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.
