Subject: ALSA: Close holes in struct snd_pcm_constraint_list
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=782e50e0b38ff284dead13265f1c3e04004e507d;p=linux-beck.git

ALSA: 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.
