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 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)
