[PATCH] ASoC: ak4642: make arrays fs_list and ps_list static const

From: Colin King
Date: Fri Jun 30 2017 - 05:17:27 EST


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

Don't populate the arrays fs_list and ps_list on the stack but make
them static const. Makes the object code smaller:

Before:
text data bss dec hex filename
12084 4888 64 17036 428c sound/soc/codecs/ak4642.o

After:
text data bss dec hex filename
11883 5032 64 16979 4253 sound/soc/codecs/ak4642.o
