[PATCH][next] ALSA: hda/ca0132: Make a const array static, makes object smaller

From: Colin King
Date: Wed May 26 2021 - 12:06:23 EST


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

Don't populate the const array dsp_dma_stream_ids the stack but instead
make it static. Makes the object code smaller by 21 bytes.

Before:
text data bss dec hex filename
189012 70376 192 259580 3f5fc ./sound/pci/hda/patch_ca0132.o

After:
text data bss dec hex filename
188927 70440 192 259559 3f5e7 ./sound/pci/hda/patch_ca0132.o

(gcc version 10.3.0)
