commit 8b706884eac958ec16518315053f77e052627084 upstream.

PCB_SYNC different than PCB_TYPE_SUPERVISOR or PCB_TYPE_DATAFRAME
should be discarded.

Irrelevant data may be forwarded up to the ndlc state machine by
phys like spi to prevent missing potential data during "write"
transactions.

commit 1d816b6eb513498aa28a0ff1e4db7632bded1707 upstream.

When receiving a NDLC PCB_SYNC_ACK the pending data was never
removed from ack_pending_q and cleared.

commit daaf1e1f1640eb11259954d1d847d8a72ab5b938 upstream.

st_nci_hci_load_session() calls kfree_skb() on unitialized
variables skb_pipe_info and skb_pipe_list if the call to
nci_hci_connect_gate() failed. Reword the error path to not use
these variables when they are not initialized. While at it, there
seemed to be a memory leak because skb_pipe_info was only freed
once, after the for-loop, even though several ones were created
by nci_hci_send_cmd.
