This saves 20 bytes on arm32, and 44 bytes on arm64. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Interestingly, making gpiod_add_lookup_table() a static inline function in <linux/gpio/machine.h> increases the caller's code size by 68 bytes on arm32. --- drivers/gpio/gpiolib.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-)
