Subject[PATCH] ASoC: rt1305: make array pd static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array pd on the stack but instead make it
static const. Makes the object code smaller by 93 bytes.

Before:
text data bss dec hex filename
38961 9784 64 48809 bea9 sound/soc/codecs/rt1305.o

After:
text data bss dec hex filename
38804 9848 64 48716 be4c sound/soc/codecs/rt1305.o

(gcc version 9.2.1, amd64)
