[PATCH] ALSA: drivers: make array 'names' const, reduces object code size

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate array 'names' on the stack but instead make them static.
Makes the object code smaller by 50 bytes:

Before:
   text    data     bss     dec     hex filename
  21237    9192    1120   31549    7b3d linux/sound/drivers/dummy.o

After:
   text    data     bss     dec     hex filename
  21095    9280    1120   31495    7b07 linux/sound/drivers/dummy.o

(gcc version 7.2.0 x86_64)
