Subject: [PATCH] au88x0: mem leak fix in snd_vortex_create()
Date: Sat, 4 Aug 2007 02:09:25 +0200	[thread overview]
Message-ID: <200708040209.25589.jesper.juhl@gmail.com> (raw)

Hi,

In sound/pci/au88x0/au88x0.c::snd_vortex_create() : 
The Coverity checker found that if we allocate storage for 'chip' 
but then leave via the  regions_out:  label, then we end up leaking 
the storage allocated for 'chip'.
I believe simply freeing 'chip' before the "return err;" line is 
all we need to fix this, but please double-check me :)
