leds: lp5521: 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 120 bytes: Before: text data bss dec hex filename 8999 4176 64 13239 33b7 drivers/leds/leds-lp5521.o After: text data bss dec hex filename 8554 4496 64 13114 333a drivers/leds/leds-lp5521.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
