Subject[PATCH] input: surface3_spi: make const array header static, reduces object code size
Date
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
