From c57cccc0382fedd95373ffdb192f45d278210686 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 21 Jan 2008 08:54:06 +0100 Subject: [PATCH] [ALSA] oxygen: optimize snd_pcm_hardware structures Add one more indirection to the lookup of the snd_pcm_hardware structures so that we can save the space of the duplicate ones.
