[PATCH] ASoC: rt5514: make array div static const, makes object smaller

From: Colin King
Date: Sun Aug 01 2021 - 02:42:15 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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)
