[PATCH][V2] ASoC: Intel: make const arrays static, reduces object code size

From: Colin King
Date: Thu Jan 24 2019 - 12:37:54 EST


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

Don't populate the const arrays on the stack but instead make
it static. Makes the object code smaller, for example:

Before:
text data bss dec hex filename
14107 8832 224 23163 5a7b bytcht_es8316.o

After:
text data bss dec hex filename
14015 8896 224 23135 5a5f bytcht_es8316.o

(gcc version 8.2.0 x86_64)

V2: also fix up bytcr_rt5640.c and bytcr_rt5651.c, thanks to
Pierre-Louis Bossart for noticing these two.
