[PATCH] ASoC: rt1308: make array pd static const, makes object smaller

From: Colin Ian King
Date: Sat Sep 07 2019 - 03:46:34 EST


Don't populate the array pd on the stack but instead make it
static const. Makes the object code smaller by 82 bytes.

Before:
text data bss dec hex filename
26548 7288 64 33900 846c sound/soc/codecs/rt1308.o

After:
text data bss dec hex filename
26370 7384 64 33818 841a sound/soc/codecs/rt1308.o

(gcc version 9.2.1, amd64)
