ALSA: drivers: make array 'names' const, reduces object code size
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) Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
