From: Colin King
Date: Sun Aug 01 2021 - 02:32:50 EST


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

Don't populate arrays on the stack but instead them static const.
Makes the object code smaller by 242 bytes.

Before:
text data bss dec hex filename
23827 8764 0 32591 7f4f ./sound/soc/sh/rcar/ssi.o

After:
text data bss dec hex filename
23361 8988 0 32349 7e5d ./sound/soc/sh/rcar/ssi.o

gcc version 10.2.0)
