[alsa-devel] [PATCH 2/2] sound: Close holes in struct snd_pcm_constraint_list

On a 64-bit system there is a 32-bit hole in struct snd_pcm_constraint_list and then 32-bit padding at the end. Reordering things slightly gets rid of the hole and padding, reducing the size of the struct by 50% from its original size.
