rockchip_drm_endpoint_is_subdriver() may also return error codes. For example if the target-node is in the disabled state, so no platform-device is getting created for it. In that case current code would count that as external rgb device, which in turn would make probing the rockchip-drm device fail. So only count the target as rgb device if the function actually returns 0.

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.
