All error/warnings: drivers/built-in.o: In function `drm_lastclose':
(.text+0x904a0): undefined reference to `drm_agp_clear'
We called drm_agp_release() in the same code-path before. How did that work without CONFIG_AGP? Ugh, *confused*
drm_agp_release() was only called if drm_core_has_AGP() was true, and that function is defined as a macro that just returns 0 when __OS_HAS_AGP isn't defined. The compiler thus optimized the drm_agp_release() call away.
