[PATCH] ALSA: hda/ca0132: make some const arrays static, makes object smaller

From: Colin King
Date: Fri Oct 16 2020 - 18:49:23 EST


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

Don't populate const arrays on the stack but instead make them
static. Makes the object code smaller by 57 bytes.

Before:
text data bss dec hex filename
173256 38016 192 211464 33a08 sound/pci/hda/patch_ca0132.o

After:
text data bss dec hex filename
172879 38336 192 211407 339cf sound/pci/hda/patch_ca0132.o

(gcc version 10.2.0)
