The HVR-1600 can do both analog and digital capture at the same time.
Due to a driver bug -EBUSY would be returned when attempting to setup an
analog capture while a digital capture was already in progress.

The tuner_warn() macro relies on the local variable "priv" to be a valid
pointer. There was a case in simple_tuner_attach() where this cannot be the
case yet, so tuner_warn() would dereference a NULL "priv" pointer. Changed
the tuner_warn() to a printk() with the originally intended output format.

This code is irrelevant to this driver and should be removed. This was
copied from a hack in cx88-dvb.c, which prevents noise coming from the
analog tuner (via an audio patch cable from the pci card to the sound
hardware) when in digital mode by muting the tda988x. This issue does
not apply to this USB hybrid chip design, where a single piece of
silicon handles both analog and digital demodulation.

a link endpoint does not have an existing session established

Some problems have been experienced in the field which cause an oops
in the pppol2tp driver if L2TP tunnels fail while passing data.
The pppol2tp driver uses private data that is referenced via the
sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes
sure that the driver uses sock_hold() when it holds a reference to the
sk pointer. This affects its sendmsg(), recvmsg(), getname(),
[gs]etsockopt() and ioctl() handlers.
Tested by ISP where problem was seen. System has been up 10 days with
no oops since running this patch. Without the patch, an oops would
occur every 1-2 days.

skb_splice_bits temporary drops the socket lock while iterating over
the socket queue in order to break a reverse locking condition which
happens with sendfile. This, however, opens a window of opportunity
for tcp_collapse() to aggregate skbs and thus potentially free the
current skb used in skb_splice_bits and tcp_read_sock.
This patch fixes the problem by (re-)getting the same "logical skb"
after the lock has been temporary dropped.

If an L2TP daemon closes a tunnel socket while packets are queued in
the tunnel's reorder queue, a kernel warning is logged because the
socket is closed while skbs are still referencing it. The fix is to

unless they are needed for new probe responses, over time the free list
would become empty and creating an adhoc network would fail due to the !
