pnp: avoid a small unlikely memory leak in proc_read_escd()
There's a small and unlikely memory leak in drivers/pnp/pnpbios/proc.c::proc_read_escd(). It's inside a sanity check, so it probably won't trigger often (if at all), however it *is* a potential leak and it's easy to avoid, so let's just fix it :) Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
