[PATCH] ISDN: Avoid a potential NULL ptr deref in ippp
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.
