Most DRM messages include three pieces of information: the type of the component (CRTC, ENCODER, CONNECTOR etc), the DRM object ID of the component, and the component name. However, there are some messages which omit the last piece of identifying information. This makes it harder to debug failures when these messages are printed, because the DRM object ID doesn't supply enough information to know which piece of hardware had a problem. Update the atomic modeset code to always print the component name along with the type and DRM object ID.

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.
