drm: Simplify drm_printk to reduce object size quite a bit
Remove function name and special " *ERROR*" from argument list $ size drivers/gpu/drm/built-in.o* (x86-32 defconfig, most drm selected) text data bss dec hex filename 5635366 182579 14328 5832273 58fe51 drivers/gpu/drm/built-in.o.new 5779552 182579 14328 5976459 5b318b drivers/gpu/drm/built-in.o.old Using "%ps", __builtin_return_address(0) is the same as "%s", __func__ except for static inlines, but it's more or less the same output. Miscellanea: o Convert args... to ##__VA_ARGS__ o The equivalent DRM_DEV_<FOO> macros are rarely used and not worth conversion Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: http://patchwork.freedesktop.org/patch/msgid/01f976d5ab93c985756fc1b2e83656fb0a2a28c8.1474856262.git.joe@perches.com
