All radio tuners in cx88 driver using same address for radio and tuner,
so there is no need to probe it twice for same tuner and we can use
radio_type UNSET, this also fix broken radio since kernel 2.6.39-rc1

90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy

14d24d148c [media] tuners: remove dvb_frontend_parameters from set_params()
This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.

After this change, very few DVBv3 specific stuff are left at the
tuners.

a824f0f445 [media] video: Drop undue references to i2c-algo-bit
There's one comment that has been copied from bttv to many other
media/video drivers:

/* init + register i2c algo-bit adapter */

Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

3f5c14d3d3 [media] drivers/media: do not use EXTRA_CFLAGS
Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425
    Author: Sam Ravnborg <sam@neptun.(none)>
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

This patch reduces the number of available choices for the notch filter type control
so that the standard-specific filter types cannot be selected. It is now limited to
being either 0 (4xFsc, the default) or 1 (square pixel optimized).
The patch also removes the initialization of this control from cx88_reset(), since
that is already done by init_controls(), which is called by cx8800_initdev().

243bf1a24d [media] cx88: properly maintain decoder config when using MPEG encoder
The cx88 driver would force core->input to always be zero when doing the
the request_acquire().  While it wasn't actually changing the input register
in the hardware, the driver makes decision based on the current input.  In
particular, it decides whether to do things like enabling the comb filter
when on a composite input but disabling it on s-video.  So for example, on
the HVR-1300, using the s-video input with the MPEG encoder would end up with
the video decoder core configured as though the input type were composite.

In short, the driver state did not match the hardware state.

This patch does two things:

1.  It forces the input to zero only if actually switching to DVB mode.  This
prevents the input from changing when the blackbird driver opens the device.

2.  Keep track of what the input was set to when switching to DVB, and reset
it back when done.  This eliminates a condition where for example the user
had the analog side of the board set to capture on the s-video input, then
he used DVB for a bit, then the analog input would unexpectedly be set to
the tuner input.

This work was sponsored by Anevia S.A.

1990d50b58 [media] Stop using linux/version.h on most video drivers
All the modified drivers didn't have any version increment since
Jan, 1 2011. Several of them didn't have any version increment
for a long time, even having new features and important bug fixes
happening.

As we're now filling the QUERYCAP version with the current Kernel
Release, we don't need to maintain a per-driver version control
anymore. So, let's just use the default.

In order to preserve the Kernel module version history, a
KERNEL_VERSION() macro were added to all modified drivers, and
the extraver number were incremented.

I opted to preserve the per-driver version control to a few
pwc, pvrusb2, s2255, s5p-fimc and sh_vou.

A few drivers are still using the legacy way to handle ioctl's.
So, we can't do such change on them, otherwise, they'll break.
Those are: uvc, et61x251 and sn9c102.

The rationale is that the per-driver version control seems to be
actively maintained on those.

Yet, I think that the better for them would be to just use the
default version numbering, instead of doing that by themselves.

While here, removed a few uneeded include linux/version.h

579b2b4512 [media] cx88: gracefully reject attempts to use unregistered cx88-blackbird driver
It should not be possible to enter mpeg_open and acquire core->lock
without the blackbird driver being registered, so just error out if it
is not.  This makes the code more readable and should prevent the bug
fixed by the patch "hold device lock during sub-driver initialization"
from resurfacing again.

Similarly, if we enter mpeg_release and acquire core->lock then either
the blackbird driver is registered (since open files keep it loaded)
or the sysadmin forced the driver's removal.  In the latter case the
state will be inconsistent and this is worth a loud warning.

1d6213ab99 [media] cx88: hold device lock during sub-driver initialization
cx8802_blackbird_probe makes a device node for the mpeg sub-device
before it has been added to dev->drvlist.  If the device is opened
during that time, the open succeeds but request_acquire cannot be
called, so the reference count remains zero.  Later, when the device
is closed, the reference count becomes negative --- uh oh.

Close the race by holding core->lock during probe and not releasing
until the device is in drvlist and initialization finished.
Previously the BKL prevented this race.

1fe70e9630 [media] cx88: fix locking of sub-driver operations
The BKL conversion of this driver seems to have gone wrong.
Loading the cx88-blackbird driver deadlocks.

The cause: mpeg_ops::open in the cx2388x blackbird driver acquires the
device lock and calls the sub-driver's request_acquire, which tries to
acquire the lock again.  Fix it by clarifying the semantics of
request_acquire, request_release, advise_acquire, and advise_release:
now all will rely on the caller to acquire the device lock.

8a317a8760 [media] cx88: protect per-device driver list with device lock
The BKL conversion of this driver seems to have gone wrong.  Various
uses of the sub-device and driver lists appear to be subject to race
conditions.

In particular, some functions access drvlist without a relevant lock
held, which will race against removal of drivers.  Let's start with
that --- clean up by consistently protecting dev->drvlist with
dev->core->lock, noting driver functions that require the device lock
to be held or not to be held.

After this patch, there are still some races --- e.g.,
cx8802_blackbird_remove can run between the time the blackbird driver
is acquired and the time it is used in mpeg_release, and there's a
similar race in cx88_dvb_bus_ctrl.  Later patches will address the
remaining known races and the deadlock noticed by Andi.  This patch
just makes the semantics clearer in preparation for those later
changes.

46e67acd5d [media] wm8775: Revert changeset fcb9757333 to avoid a regression
It seems that cx88 and ivtv use wm8775 on some different modes. The
patch that added support for a board with wm8775 broke ivtv boards with
this device. As we're too close to release 2.6.37, let's just revert
it.

1c0eb0ffb0 [media] cx88: Add RC logic for Leadtek PVR 2000
Currently, lirc-i2c has a decoding logic for Leadtek Remote
Control. Move it to cx88, as we intend to remove lirc-i2c.

For now, initialize LIRC remote keytable with RC_MAP_EMPTY, as
we don't know its keymap yet. It would be nice to later check
if is there any file on LIRC userspace with that keytable.

44c6e2a7c2 [media] cx88-dvb.c: DVB net latency using Hauppauge HVR4000
A Hauppauge HVR 4000 is used on a School On Internet Asia (SOI Asia)
project in order to carry IP traffic over ULE. However, there is an
issue with high latency jitter.

My boss, Husni, identified the problem and provided a patch for it.

The default buffer size of 32 TS frames on cx88 causes the high latency,
so our deployment changes that to 6 TS frames. This patch made the
buffer size tunable, while keeping the default buffer size of 32 TS
frames unchanged.

6bda96447c [media] rc: rename the remaining things to rc_core
The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
	- ir-core.h to rc-core.h
	- IR_CORE to RC_CORE
	- namespace inside rc-core.c/rc-core.h

To be consistent with the other changes.

No functional change on this patch.

d8b4b5822f [media] ir-core: make struct rc_dev the primary interface
This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.

This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.

The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()
