Remove near duplication of format string constants by using the newly introduced vsprintf extention %pV to reduce text by 20k or so. $ size drivers/net/mlx4/built-in.o* text data bss dec hex filename 161367 1866 48784 212017 33c31 drivers/net/mlx4/built-in.o 142621 1866 46248 190735 2e90f drivers/net/mlx4/built-in.o.new Use printk_once as appropriate. Convert printks to pr_<level>, some bare printks now use pr_cont. Remove now unused #define PFX. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
