[PATCH] ASoC: rt1011: make array pd static const, makes object smaller

From: Colin King
Date: Sat Sep 07 2019 - 03:38:07 EST


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

Don't populate the array pd on the stack but instead make it
static const. Makes the object code smaller by 100 bytes.

Before:
text data bss dec hex filename
51463 13016 128 64607 fc5f sound/soc/codecs/rt1011.o

After:
text data bss dec hex filename
51299 13080 128 64507 fbfb sound/soc/codecs/rt1011.o

(gcc version 9.2.1, amd64)
