From: Colin Ian King <colin.king@canonical.com>

Don't populate the array seq on the stack, instead make it static.
Makes the object code smaller by over 1100 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   6152	   1216	     64	   7432	   1d08	drivers/input/mouse/byd.o

After:
   text	   data	    bss	    dec	    hex	filename
   4974	   1280	     64	   6318	   18ae	drivers/input/mouse/byd.o
