From 3daa7ea650d59ae86926f0ced4c4ccd99ab33fda Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 6 Jan 2011 22:19:47 +0100 Subject: [PATCH] ALSA: Don't leak in sound/core/oss/pcm_oss.c::snd_pcm_hw_param_near() snd_pcm_hw_param_near() will leak the memory allocated to 'save' if the call to snd_pcm_hw_param_max() returns less than zero. This patch makes sure we never leak.
