gpio: 104-dio-48e: make array 'ports' static, shrinks object size
Don't populate the const read-only array 'ports' on the stack but instead make it static. Makes the object code smaller by over 100 buytes: Before: text data bss dec hex filename 10959 4952 832 16743 4167 drivers/gpio/gpio-104-dio-48e.o After: text data bss dec hex filename 10790 5008 832 16630 40f6 drivers/gpio/gpio-104-dio-48e.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: William Breathitt Gray <vilhelm.gray@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
