media: pci: cx23885: handle adding to list failure

Browse source

[ Upstream commit c5d59528e2 ]

altera_hw_filt_init() which calls append_internal() assumes
that the node was successfully linked in while in fact it can
silently fail. So the call-site needs to set return to -ENOMEM
on append_internal() returning NULL and exit through the err path.

Fixes: 349bcf02e3 ("[media] Altera FPGA based CI driver module")
