There's a potential problem in isdn_ppp.c::isdn_ppp_decompress().
dev_alloc_skb() may fail and return NULL. If it does we will be passing a
NULL skb_out to ipc->decompress() and may also end up
dereferencing a NULL pointer at
*proto = isdn_ppp_strip_proto(skb_out);
Correct this by testing 'skb_out' against NULL early and bail out.
