Hi,

The Coverity checker spotted that we do not always remember to call va_end() on 'args' in failure paths in snd_pcm_hw_rule_add(). Here's a patch to fix that up (compile tested only) - it also removes some annoying trailing whitespace that caught my eye while I was in the area..

Signed-off-by: Jesper Juhl jj@chaosbits.net

Thanks, applied now.
