leds: lp5562: make several arrays static const
Don't populate the arrays on the stack, instead make them static const. Makes the object code smaller by over 150 bytes: Before: text data bss dec hex filename 7725 2448 64 10237 27fd drivers/leds/leds-lp5562.o After: text data bss dec hex filename 7184 2832 64 10080 2760 drivers/leds/leds-lp5562.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
