Use a single mechanism to show driver version. Reduces text a tiny bit too. Remove uses of static int printed_version Add and use ata_print_version(const struct device *, const char *ver) and ata_print_version_once. $ size drivers/ata/built-in.* text data bss dec hex filename 544969 73893 116584 735446 b38d6 drivers/ata/built-in.allyesconfig.ata.o 543870 73893 116592 734355 b34ad drivers/ata/built-in.allyesconfig.print_once.o 141328 14689 4220 160237 271ed drivers/ata/built-in.defconfig.ata.o 141212 14689 4220 160121 27179 drivers/ata/built-in.defconfig.print_once.o Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
