drm: Reduce object size of DRM_DEV_<LEVEL> uses
These macros are similar to the DRM_<LEVEL> with the addition of a struct device * to the arguments. Convert the single drm_dev_printk function into 2 separate functions. drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg for conditional masked use. Remove the __func__ argument and use __builtin_return_address(0) to be similar to the DRM_<LEVEL> macros uses. Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments and use a consistent style. These macros are rarely used in the generic gpu/drm code so the code size does not change much for a defconfig, but when more drivers are enabled, there is ~4k savings. Many of these macros have no existing use at all. $ size -t drivers/gpu/drm/built-in.a | tail -1 1877530 44651 995 1923176 1d5868 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 1877527 44651 995 1923173 1d5865 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17166750 2689238 108352 19964340 130a1b4 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17168888 2691734 108352 19968974 130b3ce (TOTALS) Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/e5c164946e15375ac71b69b75f296efdf0b76e6d.1521233717.git.joe@perches.com
