ASoC: rl6231: make arrays div and pd static const, reduces object code size
Don't populate the read-only arrays div and pd on the stack, instead make them static const. Makes the object code smaller by 210 bytes: Before: text data bss dec hex filename 2869 720 0 3589 e05 sound/soc/codecs/rl6231.o After: text data bss dec hex filename 2495 880 0 3375 d2f sound/soc/codecs/rl6231.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Mark Brown <broonie@kernel.org>
