V4L/DVB (6346): ivtvfb: YUV output size fix when ivtvfb is not loaded
If the ivtvfb module isn't loaded, the valid YUV output area should be set to
full-screen. This patch fixes the case where the valid output area was not
reset when the output broadcast format was changed from NTSC to PAL. This
resulted in output being limited to the top 480 lines of the display.

V4L/DVB (6345): ivtvfb: YUV handling of an image which is not visible in the display area
When the ivtvfb module is loaded, the YUV output is relative to the
framebuffer output. When a virtual screen size is used, the output area for
the YUV may actually be off screen. To prevent the hardware from crashing,
the current driver will ignore an off-screen position and leave the output
visible at the last on-screen position. This may not be desirable, so this
patch will switch off the YUV output should the image move off-screen, and
re-enable it should the image move on-screen again.

This patch partially reverts a previous change that caused the

Unfortunately, another firmware call on the PVR350 sometimes scrambles the

the CX2341X_OSD_SET_PIXEL_FORMAT calls to try and prevent this from

V4L/DVB (6336): cx8802: Plug memory leak when unregistering a driver
When a cx8802 sub-driver was unregistered, the struct cx8802_driver, which was
kmalloc()ed by cx8802_register_driver(), was deleted from the list of drivers,
but never freed.

V4L/DVB (6334): cx88: Change (struct cx8802_dev)->drvlist to a list_head and fix bugs
It was a struct cx8802_driver for no apparent reason. Nothing uses a
cx8802_driver in the cx8802_dev struct. The only field that was used was
devlist, a list_head.
The code in cx8802_remove() that removed any loaded sub-drivers was broken.
It would delete the current list entry, but didn't use list_for_each_safe. It
also called list_del() on the list _head_ inside the list_for_each loop? It
would crash if it was run, which I don't think can ever happen.
Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded
first. So there isn't any way for a sub-driver to still be loaded when
cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes
the PCI card while the drivers are loaded?
So I left some code in to handle that if it's actually possible. It will
remove the sub-drivers from the device cx8802_remove() was called on, and only
that device. If one has two DVB cards and unplugs one, there is no reason to
unload the DVB drivers for both cards. I have no way to test this, but it
can't be worse than what was there before.
cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested
driver on that device. It first loops over the cx8802 device list looking for
the device it was passed, which is pointless. It doesn't need to find the
device pointer in the list, as it already has the pointer.
The list_head in the cx8802_driver struct, which joins all the _drivers_
attached to a device, was named devlist. Changed that to drvlist, since the
devlist is used for a list of _devices_ in other cx8802 structs.

Make the field conditional on VP3045 support. It was already conditional on

Add two mute controls. One mutes everything, the other just mutes the analog
pass-through output.
Rename the existing volume control. The controls are now:
Playback Volume
Playback Switch
Capture Switch
These names might seem odd, but I believe they are more correct. The previous
"Capture Volume" control didn't actually effect the volume of the captured
audio. Instead it controls the volume of the analog pass-thought output. It
appears that pass-through controls like this are usually considered to be in
the playback direction, not capture. For example, "CAPTURE feedback Playback
Volume" is the name used for a control that appears to have the same effect in
the ca0106 driver. We only have one volume control, so we can omit the
"CAPTURE feedback" part.
If someone where to add PCM playback support to the driver, then this would be
the volume control.

[PATCH] audit: watching subtrees
New kind of audit rule predicates: "object is visible in given subtree".
The part that can be sanely implemented, that is. Limitations:
* if you have hardlink from outside of tree, you'd better watch
it too (or just watch the object itself, obviously)
* if you mount something under a watched tree, tell audit
that new chunk should be added to watched subtrees
* if you umount something in a watched tree and it's still mounted
elsewhere, you will get matches on events happening there. New command
tells audit to recalculate the trees, trimming such sources of false
positives.
Note that it's _not_ about path - if something mounted in several places
(multiple mount, bindings, different namespaces, etc.), the match does
_not_ depend on which one we are using for access.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.
