The default_mode_mask global is replaced by a list of tuner structs. The
tuner driver now walks that list to see which radio and/or tv tuner
devices are registered to a given i2c adapter.
The default_mode_mask global had to go since this is no longer supported
with the new bus-based I2C API.

To ensure prevention of detecting a tda9885/6/7 as a tda8290 or tda8295, we

The attached patch modifies the em28xx driver so that there can be ioctls from
multiple different threads.
This is necessary for capture apps like MPlayer that use different threads for
capturing and channel tuning.
Now the locking is only done for the ioctls that change properties of the
device or access the i2c bus.
It also removes some locks that look unnecessary:
In em28xx_init_dev:
the videodevice is not registered yet so nothing can access the hardware
meanwhile, the device struct is not assigned to the interface yet so no race
with disconnect is possible
In em28xx_release_resources:
it gets only called when dev->lock is already held

The ttpci Kconfig file has bugs that cause it to fail in certain Kconfig
situations. The basic problem is that it selects certain drivers, but does
not depend on the dependencies of those drivers.
See http://article.gmane.org/gmane.comp.video.video4linux/35072
Using the Kconfig file also has some annoyances. For instance one can't turn
off AV7110 support unless you go down several options and first turn off
budget-patch support. Normally user selectable drivers are not forced on like
this.
The "AV7110 cards with Budget Patch" option is disabled if "Budget cards"
isn't on. Normally a driver appears nested under a driver it depends on, but
since drivers that don't depend on "Budget cards" are between the two options,
the config programs can't display the tree correctly.
The Makefile has an issue too. Some modules, ttpci-eeprom and budget-core,
appear in the Makefile under several different config symbols. If more than
one of these symbols is on, they will get added the to list of objects
multiple times. The normal convention is to have a config symbol just the
common object(s) and have the users of the that object either depend on or
select that config symbol.
This patch fixes all these issues. ttpci-eepom is under a new config symbol,
and so is the budget-core module. The four different budget card types appear
as sub-drivers under a main "SAA7146 DVB cards" option. Turning on
budget-patch doesn't force AV7110. Drivers using SAA7146_VV have the
necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV
without V4L being on.

In some designs, the tuner silicon may be on an i2c bus behind an i2c gate,
controlled by the analog demodulator. We already have a method to control
such i2c gates when they are controlled by the digital demodulator, but in
some hybrid designs, there may be an i2c gate controlled by each demodulator.
For example, when in analog tuning mode, one would access the tuner by opening
the i2c gate controlled by the analog demodulator, while when in digital
tuning mode, one would access the tuner by opening the i2c gate controlled by
the digital demodulator.
We must add this callback function to analog_tuner_ops in order to handle

tea5767 has several possible configurations. Before the patch, the

Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).
This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

This can be broken down into these major areas:
- Documentation updates (language translations and fixes, as
well as kobject and kset documenatation updates.)
- major kset/kobject/ktype rework and fixes. This cleans up the
kset and kobject and ktype relationship and architecture,
making sense of things now, and good documenation and samples
are provided for others to use. Also the attributes for
kobjects are much easier to handle now. This cleaned up a LOT
of code all through the kernel, making kobjects easier to use
if you want to.
- struct bus_type has been reworked to now handle the lifetime
rules properly, as the kobject is properly dynamic.
- struct driver has also been reworked, and now the lifetime
issues are resolved.
- the block subsystem has been converted to use struct device
now, and not "raw" kobjects. This patch has been in the -mm
tree for over a year now, and finally all the issues are
worked out with it. Older distros now properly work with new
kernels, and no userspace updates are needed at all.
- nozomi driver is added. This has also been in -mm for a long
time, and many people have asked for it to go in. It is now
in good enough shape to do so.
- lots of class_device conversions to use struct device instead.
The tree is almost all cleaned up now, only SCSI and IB is the
remaining code to fix up...

All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

We save the current state in the object itself, so we can do proper
cleanup when the last reference is dropped.
If the initial reference is dropped, the object will be removed from
sysfs if needed, if an "add" event was sent, "remove" will be send, and
the allocated resources are released.
This allows us to clean up some driver core usage as well as allowing us
to do other such changes to the rest of the kernel.

This moves the block devices to /sys/class/block. It will create a
flat list of all block devices, with the disks and partitions in one
directory. For compatibility /sys/block is created and contains symlinks
to the disks.

We should remove the glue directory between the class and the bus
device _after_ we sent out the 'remove' event for the device, otherwise
the parent relationship is no longer valid, and composing the path
with deleted sysfs entries will not work.

This patch (as1013) was suggested by David Woodhouse; it fixes a race
in the driver core. If a device is unregistered at the same time as
its driver is unloaded, the driver's code pages may be unmapped while
the remove method is still running. The calls to get_driver() and
put_driver() were intended to prevent this, but they don't work if the
driver's module count has already dropped to 0.
Instead, the patch keeps the device on the driver's list until after
the remove method has returned. This forces the necessary
synchronization to occur.

The driver core debugging messages are a mess. This provides a unified
message that makes them actually useful.
The format for new kobject debug messages should be:
driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n
Note, the class code is not changed in this patch due to pending patches
in my queue that this would conflict with. A later patch will clean
them up.

This patch removes the kobject, and a few other driver-core-only fields
out of struct driver and into the driver core only. Now drivers can be
safely create on the stack or statically (like they currently are.)

The module driver specific code should belong in the driver core, not in
the kernel/ directory. So move this code. This is done in preparation
for some struct device_driver rework that should be confined to the
driver core code only.
This also lets us keep from exporting these functions, as no external
code should ever be calling it.
Thanks to Andrew Morton for the !CONFIG_MODULES fix.

The iseries driver wants to hang kobjects off of its driver, so, to
preserve backwards compatibility, we need to add a call to the driver
core to allow future changes to work properly.
Hopefully no one uses this function in the future and the iseries_veth
driver authors come to their senses so I can remove this hack...

Make the ipath driver use the new driver functions so that it does not
touch the sysfs portion of the driver structure.
We also remove the redundant symlink from the device back to the driver,
as it is already in the sysfs tree. Any userspace tools should be using
the standard symlink, not some driver specific one.

The PCI bus should not be trying to declare its own attribute type.
Especially as this code could never ever be called because the driver
core overwrites the driver kobject type to be its own internal type.
Delete all of this code as it was never being used and is not correct.
Also update my copyright on the file while I'm touching things there.

struct bus_type is static everywhere in the kernel. This moves the
kobject in the structure out of it, and a bunch of other private only to
the driver core fields are now moved to a private structure. This lets
us dynamically create the backing kobject properly and gives us the
chance to be able to document to users exactly how to use the struct
bus_type as there are no fields they can improperly access.
Thanks to Kay for the build fixes on this patch.

This allows an easier way to get to the device klist associated with a
struct bus_type (you have three to choose from...) This will make it
easier to move these fields to be dynamic in a future patch.
The only user of this is the PCI core which horribly abuses this
interface to rearrange the order of the pci devices. This should be
done using the existing bus device walking functions, but that's left
for future patches.
