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. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
