As reported by Jan, and others over the past few years, there is a
race condition caused by unix_release setting the sock->sk pointer
to NULL before properly marking the socket as dead/orphaned. This
can cause a problem with the LSM hook security_unix_may_send() if
there is another socket attempting to write to this partially
released socket in between when sock->sk is set to NULL and it is
marked as dead/orphaned. This patch fixes this by only setting
sock->sk to NULL after the socket has been marked as dead; I also
take the opportunity to make unix_release_sock() a void function
as it only ever returned 0/success.
Dave, I think this one should go on the -stable pile.
Special thanks to Jan for coming up with a reproducer for this
problem.

With the addition of following patch:
fcf8058 cpufreq: Simplify cpufreq_add_dev()
cpufreq driver's .init() routine must initialize policy->cpus with
mask of all possible CPUs (Online + Offline) that share the clock.
Then the core would copy this mask onto policy->related_cpus and will
reset policy->cpus to carry only online cpus.
acpi-cpufreq driver wasn't updated with this assumption and so
sometimes when we try to hot[un]plug CPUs at run time, sysfs
directories get corrupted.
This patch fixes acpi-cpufreq driver against this corruption.

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.

As a consequence the ioctl op has been replaced by unlocked_ioctl.
Since we are now using the core lock the locking scheme has been
simplified as well.
The main reason for converting this driver to vb2 was that the locking
scheme in v4l2.c was hopeless. It was easier to just convert the driver
then to try and salvage a threading and videobuf nightmare.
The videobuf2 framework is far, far superior compared to the old videobuf.

All fields in solo_enc_fh do not belong there since they refer to global
properties. After moving all these fields to solo_enc_dev the solo_dev_fh
struct can be removed completely.
Note that this also kills the 'listener' feature of this driver. This
feature (where multiple filehandles can read the video) is illegal in the
V4L2 API. Do this in userspace: it's much more efficient to copy memory
than it is to DMA to every listener.
