From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array header on the stack, instead make it static. Makes the object code smaller by over 180 bytes:
Before: text data bss dec hex filename 6003 1536 0 7539 1d73 surface3_spi.o
After: text data bss dec hex filename 5726 1632 0 7358 1cbe surface3_spi.o
