96de0e252c Convert files to UTF-8 and some cleanups
* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

ba25f9dcc4 Use helpers to obtain task pid in printks
The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

Introduce freezer-friendly wrappers around wait_event_interruptible() and
wait_event_interruptible_timeout(), originally defined in <linux/wait.h>, to

This is necessary for the freezer to stop sending signals to kernel threads,

7eff2e7a8b Driver core: change add_uevent_var to use a struct
This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

There is one list_for_each+list_entry in cpia_pp.c that
wasn't changed because it expects the loop iterator to remain NULL if
the list is empty.

A bug in vivi is fixed; the 'safe' version needs to be used because the loop
deletes the list entries.

CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB.

But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB
or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver.

The reference in cx23885.h should just be removed, as the code there needs to
be included if DVB is on or off.  I do not think you can even compile the
cx23885 driver without DVB.  It's clearly just leftover from when the file was
obvious copied from the cx88 driver (which is not mentioned in the copyright
BTW).

The reading/streaming fields are used for mutual exclusion of the queue and
should be protected by the queue lock.

ba32bd95d4 V4L/DVB (6275): V4L: vivi.c remove the "resource" locking
The "resource" locking in vivi isn't needed since
streamon/streamoff/read_stream do mutual exclusion using
q->reading/q->streaming.

Plus it is sort of broken:

a) res_locked() use in vivi_read() is racey.
b) res_free() calls mutex_lock twice causing streamoff to break

85c7c70bc2 V4L/DVB (6274): V4L: vivi.c replace logic in vivi_poll with videobuf_poll_stream
Since vivi is using videobuf_read_stream() it can use videobuf_poll_stream()
now.

If the client provides V4L2_FIELD_ANY vivi should return a valid field :)
