Incorrectly spelled CFLAGS- failed to add -DDYNAMIC_DEBUG_MODULE,
which disabled dynamic-debug in modules built with:
CONFIG_DYNAMIC_DEBUG=n # 1
CONFIG_DYNAMIC_DEBUG_CORE=y # 2
CONFIG_DRM_USE_DYNAMIC_DEBUG=y # 3
NB: this adds the flag (when 3) more often than strictly needed;
modules built with CONFIG_DYNAMIC_DEBUG=y (!1) don't need the flag.
Fixes: 84ec67288c10 ("drm_print: wrap drm_*_dbg in dyndbg descriptor factory macro")
