gpio: make several const arrays static, shrinks object size
Don't populate the const read-only arrays 'port' on the stack but instead make them static. Makes the object code smaller: Before: text data bss dec hex filename 8542 4088 672 13302 33f6 drivers/gpio/gpio-gpio-mm.o 10959 4952 832 16743 4167 drivers/gpio/gpio-104-dio-48e.o 9022 5064 1408 15494 3c86 drivers/gpio/gpio-104-idi-48.o After: text data bss dec hex filename 8372 4144 672 13188 3384 drivers/gpio/gpio-gpio-mm.o 10790 5008 832 16630 40f6 drivers/gpio/gpio-104-dio-48e.o 8853 5152 1408 15413 3c35 linux/drivers/gpio/gpio-104-idi-48.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>
