Convert the single drm_dev_printk function into 2 separate functions. drm_dev_printk with a KERN_ * 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_ macros uses. Convert the DRM_DEV_ 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 --- drivers/gpu/drm/drm_print.c | 37 +++++++++++++----- include/drm/drm_print.h | 94 ++++++++++++++++++++++----------------------- 2 files changed, 74 insertions(+), 57 deletions(-) diff --git a/drivers/gpu/drm/drm_print.c b/drivers/gpu/drm/drm_print.c index 79abf6d5b4db..b25f98f33f6c 100644 --- a/drivers/gpu/drm/drm_print.c +++ b/drivers/gpu/drm/drm_print.c @@ -63,16 +63,34 @@ void drm_printf(struct drm_printer *p, const char *f, ...) } EXPORT_SYMBOL(drm_printf);
