There's a problem in drivers/bluetooth/dtl1_cs.c::dtl1_hci_send_frame()
If bt_skb_alloc() returns NULL, then skb_reserve(s, NSHL); will cause a
NULL pointer deref - ouch. If we can't allocate the resources we require
we need to tell the caller by returning -ENOMEM.
Found by the coverity checker as bug #409

While reviewing the IRQ autoprobing code i found the attached buglet.
probe_irq_on()/off() calls must always be in pairs, because the generic IRQ
code uses a global semaphore to serialize all autoprobing activites.
(which does make sense) The ARM code's probe_irq_*() implementation does
not do this, but if this driver is ever used on another platform, this bug
might bite.
(It probably does not trigger in practice, because a zero probing mask
returned should be rare - but still.)

V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in
an MPEG stream. Currently only one format is supported: the format designed
for the ivtv driver. This should be extended with new standard formats
(such as defined for DVB) in the future.

Fixes the weird and incorrect condition in VIDIOC_S_FREQUENCY.
The tuner should always be switched to the mode specified in the
v4l2_frequency struct. Much simpler and also corresponding to the
v4l2 specification.
The old condition made it impossible to switch from radio to
analog tv mode using VIDIOC_S_FREQUENCY. Instead the (tv) frequency would
be given to the radio tuner.

The cx2341x mpeg encoder module is used by cx88-blackbird, pvrusb2 and
the external ivtv driver. This patch allows for cx2341x to be selected without
having to also select cx88-blackbird. This will be needed to build the external
ivtv driver or the standalone pvrusb2 driver against kernel 2.6.18

i386 assembly has more compact instructions for accessing 7-bit offsets.
So by moving the large members to the end of the structure we can save
quite a bit of code size. This patch shaves about 10% or 300 bytes off
the padlock-aes file.

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).
However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.
This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.

Name, phys and uniq are quite often constant strings in moules implementing
particular input device. If a module unregisters input device and then gets
unloaded, the device could still be present in memory (pinned via sysfs),
but aforementioned members would point to some random memory. Set them all
to NULL when unregistering so sysfs handlers won't try dereferencing them.
