Allocate zoran devices dynamically. Currently, the zr36067 driver
stores the device structures in a global array, with room for 4
devices. This makes the bss section very large (90 kB!), and given
that most users, I suspect, have only one zoran device, this is a
waste of kernel memory. Allocating the memory dynamically lets us use
only the amount of memory we need.

Although the V4L2 spec states that the minimum and maximum fields may not be
valid for control types other than V4L2_CTRL_TYPE_INTEGER, it makes sense
to set the bounds to 0 and 1 for boolean controls instead of returning
uninitialized values.

From: Simon Arlott <simon@fire.lp0.eu>
When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.
Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.
My card's tuner is configured with autodetection from eeprom, so I don't
need to manually set the tuner. I've checked that the autodetection still
works for my card.

From: Laurent Pinchart <laurent.pinchart@skynet.be>
The uvcvideo driver's uvc_v4l2_open() method is called from videodev's
video_open() function, which means it is called with the videodev_lock
mutex held. uvc_v4l2_open() then takes uvc_driver.open_mutex to check
dev->state and avoid racing against a device disconnect, which means
that open_mutex must nest inside videodev_lock.
However uvc_disconnect() takes the open_mutex around setting
dev->state and also around putting its device reference. However, if
uvc_disconnect() ends up dropping the last reference, it will call
uvc_delete(), which calls into the videodev code to unregister its
device, and this will end up taking videodev_lock. This opens a
(unlikely in practice) window for an AB-BA deadlock and also causes a
lockdep warning because of the lock misordering.
Fortunately there is no apparent reason to hold open_mutex when doing
kref_put() in uvc_disconnect(): if uvc_v4l2_open() runs before the
state is set to UVC_DEV_DISCONNECTED, then it will take another
reference to the device and kref_put() won't call uvc_delete; if
uvc_v4l2_open() runs after the state is set, it will run before
uvc_delete(), see the state, and return immediately -- uvc_delete()
does uvc_unregister_video() (and hence video_unregister_device(),
which is synchronized with videodev_lock) as its first thing, so there
is no risk of use-after-free in uvc_v4l2_open().
Bug diagnosed based on a lockdep warning reported by Romano Giannetti

compatibility to not work at all, this release fixes this
* Some apps (xawtv, kopete) use an ioctl wrapper internally for various
reasons. This wrappers request argument is an int, but the real ioctl's
request argument is an unsigned long. Passing the VIDIOC_xxx defines through
to the wrapper, and then to the real ioctl, causes the request to get sign
extended on 64 bit args. The kernel seems to ignore the upper 32 bits,
causing the sign extension to not make a difference. libv4l now also
ignores the upper 32 bits of the libv4lx_ioctl request argument on 64 bit
archs
