drm: drop obsolete drm_core.h
The drm_core.h header contains a set of constants meant to be used
throughout DRM. However, as it turns out, they're each used just once and
don't bring any benefit. They're also grossly mis-named and lack
name-spacing. This patch inlines them, or moves them into drm_internal.h
as appropriate:
- CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*()
macros. It's just confusing having to follow 2 pointers when trying to
find the definition of these fields. Grep'ping for MODULE_AUTHOR()
should reveal the full information, if there's no strong reason not to.
- CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are
inlined into the sysfs 'version' attribute. They're stripped
everywhere else (which is just some printk() statements). CORE_NAME
just doesn't make *any* sense, as we hard-code it in many places,
anyway. The other constants are outdated and just serve
binary-compatibility purposes. Hence, inline them in 'version' sysfs
attribute (we might even try dropping it..).
- DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're
only used by the global ioctl handlers. Furthermore, versioning
interfaces breaks backports and as such is deprecated, anyway. We just
keep them for historic reasons. I doubt anyone will ever modify them
again.
