The commit 651e3dc6dd58a79c90db7513ee2fb28360a4560d, "drm: Fix
compilation on 2.6.30" broke all builds on kernels before 2.6.26.
Variadic functions cannot be inlined.

The variadic inline function is replaced with a variadic macro.

Also, the function dev_name() added by that same commit is never used,
so it is removed.

This fixes DRM compilation of nouveau.ko on kernel 2.6.30.

Patch allows the backlight to be manipulated under gnome on apple powerpc
based NV30 machines.  It works fine on my powerbook, and should also work
for older NV17/NV18 machines.

Note that older powerpc specific tools (pbbuttonsd) have some problems with
this implementation (because the device is not yet there at the start time
of the daemon, and the code makes incorrect assumptions about the max
brightness values). However, IMHO these things can and should be addressed
in the daemon.

Some style/warning fixes applied by Stuart Bennett <stuart@freedesktop.org>

Avoid failure to build on old kernels with CONFIG_BACKLIGHT_CLASS_DEVICE set

This may prevent a possible panic on shutdown.

This also means, that DRM_FULL_MM_COMPAT is always defined,
so it is dropped, too.
