From: Colin Ian King <redacted> Don't populate the array stpa on the stack but instead it static const. Makes the object code smaller by 81 bytes: Before: text data bss dec hex filename 54993 17248 0 72241 11a31 ./drivers/net/ethernet/ti/cpsw_new.o After: text data bss dec hex filename 54784 17376 0 72160 119e0 ./drivers/net/ethernet/ti/cpsw_new.o (gcc version 10.3.0) Signed-off-by: Colin Ian King <redacted> --- drivers/net/ethernet/ti/cpsw_new.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
