Even though the components framework can handle duplicate entries, the extra entries cause a lot more debug messages to be generated, which would be confusing to developers not familiar with our driver and the framework in general. Instead, we can scan the relatively small queue and check if the component to be added is already queued up. Since the display pipelines are symmetrical (not considering the third display pipeline on the A80), and we add components level by level, when we get to the second instance at the same level, any shared downstream components would already be in the queue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
