Subject[PATCH] mfd: stw481x: make three arrays static const, reduces object code size
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the arrays vcore_val, vpll_val and vaux_val on the
stack, instead make them static const. Makes the object code smaller
by over 370 bytes:

Before:
text data bss dec hex filename
6971 3248 64 10283 282b drivers/mfd/stw481x.o

After:
text data bss dec hex filename
6338 3504 64 9906 26b2 drivers/mfd/stw481x.o
