change drm_dev_dbg & drm_dbg to macros, which forward to the renamed functions (with __ prefix added). Those functions sit below the categorized layer of macros implementing the DRM debug.category API, and implement most of it. These are good places to insert dynamic-debug jump-label mechanics, which will allow DRM to avoid the runtime cost of drm_debug_enabled(). no functional changes. memory cost baseline: (unchanged) bash-5.1# drms_load [ 9.220389] dyndbg: 1 debug prints in module drm [ 9.224426] ACPI: bus type drm_connector registered [ 9.302192] dyndbg: 2 debug prints in module ttm [ 9.305033] dyndbg: 8 debug prints in module video [ 9.627563] dyndbg: 127 debug prints in module i915 [ 9.721505] AMD-Vi: AMD IOMMUv2 functionality not available on this system - This is not a bug.

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.
