From: Colin Ian King <colin.king at canonical.com>
Don't populate the array div on the stack but instead it
static const. Makes the object code smaller by 48 bytes.
Before:
text data bss dec hex filename
53894 16368 128 70390 112f6 ./sound/soc/codecs/rt5514.o
After:
text data bss dec hex filename
53750 16464 128 70342 112c6 ./sound/soc/codecs/rt5514.o
(gcc version 10.2.0)
