upgrade the callchain to drm_dbg() and drm_dev_dbg(); add a struct _ddebug ptr parameter to them, and supply that additional param by replacing the '_no_desc' flavor of dyndbg Factory macro currently used with the flavor that supplies the descriptor. NOTES: The descriptor gives these fns access to the decorator flags, but they do none of the dynamic-prefixing done by dynamic_emit_prefix(), which is currently static. DRM already has conventions for logging/messaging; just tossing optional decorations on top probably wouldn't help. Instead, existing flags (or new ones, perhaps 'sd' ala lspci) can be used to make current message conventions optional. This suggests a new drmdbg_prefix_emit() to handle prefixing locally. For CONFIG_DRM_USE_DYNAMIC_DEBUG=N, just pass null descriptor. desc->class_id is redundant with category parameter, but its availability is dependent on desc.

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.
