[PATCH] ASoC: mediatek: mt8195: make array adda_dai_list static const

From: Colin King
Date: Wed Sep 15 2021 - 06:50:36 EST


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

Don't populate the array adda_dai_list on the stack but instead it
static const. Also makes the object code smaller by 33 bytes:

Before:
text data bss dec hex filename
28271 11640 0 39911 9be7 mt8195/mt8195-dai-adda.o

After:
text data bss dec hex filename
28142 11736 0 39878 9bc6 mt8195/mt8195-dai-adda.o

(gcc version 11.2.0)
