OmniVision sensors are used as well in Empiatech based cameras such as the
"SpeedLink Vicious And Devine Laplace" webcam (EM2765 + Omnivision OV2640).
With this patch applied, OminiVision sensors with 8 bit address and register
width are detected (recent models have a 16 bit address width and use different
client addresses).
The most commonly used sensors (including the ones listed by Empiatech) are
detected properly, although there is no support for them yet.

Sensor detection and initialization/configuration are currently mixed together.
This works as long as all devices with a particular sensor are working with the
same board configuration. In the long run, this will be not sufficient, so
separate these both steps to make the code more flexible and future proof.
This also makes the code more consistent, because the initialization of the
MT9V011 sensor subdevice is already separated.

The current board hint code is mixed together with the sensor detection and
initialization code. It actually selects a board depending on the detected
sensor type only, with the result that 3 of the 6 webcam boards are currently
dead.
Separate it and move it to em28xx_hint_board() which already contains the board
hints for analog capturing+TV and DVB devices.
This way, we have all board hints at a common place which makes it easier
to extend the code and reduces the risk of regressions.
It also makes it possible again to use the boards EM2750_BOARD_DLCW_130,
EM2820_BOARD_VIDEOLOGY_20K14XUSB and EM2860_BOARD_NETGMBH_CAM (using the module
parameter "card").

The webcam "SpeedLink VAD Laplace" (em2765 + ov2640) uses a special algorithm
for i2c communication with the sensor, which is connected to a second i2c bus.
We don't know yet how to find out which devices support/use it.
It's very likely used by all em25xx and em276x+ bridges.
Tests with other em28xx chips (em2820, em2882/em2883) show, that this
algorithm always succeeds there although no slave device is connected.
The algorithm likely also works for real i2c client devices (OV2640 uses SCCB),
because the Windows driver seems to use it for probing Samsung and Kodak
sensors.

Since commit a1fd287780:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:
@@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {
/* totalwidth */ 1135,
/* sqwidth */ 944,
/* vdelay */ 0x20,

},{
.v4l2_id = V4L2_STD_NTSC_M | V4L2_STD_NTSC_M_KR,
.name = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
touch the .cropcap.defrect.height value at all) by 2, where as the fixed
code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
now is done twice for .cropcap.bounds.height, and also is applied to
.cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.

If the tuner frontend does not support get_rf_strength, then don't set

Both callbacks overwrite the signal and afc fields of struct v4l2_tuner
but that should only happen if the tuner can actually detect this. If
it can't, then it should leave those fields alone so other subdevices
can try and detect the signal/afc.
This fixes the bug where the au8522 detected a signal and then tuner-core

Just checking if the op exists isn't correct, you should check if the ioctl
is valid (which implies that the op exists as well).
One exception is g_std: if current_norm is non-zero, then the g_std op may be
absent. This sort of weird behavior is one of the reasons why I am trying to
get rid of current_norm.
This patch fixes the case where the g/s_std op is set, but these ioctls are
disabled. This can happen in drivers supporting multiple models, some that
have TV input (and support the STD API) and some that have a sensor (and do
not support the STD API). In the latter case qv4l2 would still show the

When calling v4l2_ctrl_add_handler(), lockdep would detect a potential
recursive locking problem on a situation that is by design intended and
not a recursive lock. This happened because all struct
v4l2_ctrl_handler.lock mutexes were created as members of the same lock
class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the
hdl->lock on two different v4l2_ctrl_handler instances.
This change breaks the large lockdep lock class for struct
v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler
instantiation specific lock classes with meaningful class names.
This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking
validation, as long as the relationships between drivers adding v4l2
controls to their own handler from other v4l2 drivers' control handlers
remains straightforward.
struct v4l2_ctrl_handler.lock lock classes are created with names such
that the output of cat /proc/lockdep indicates where in the v4l2 driver
code v4l2_ctrl_handle_init() is being called on instantiations:
ffffffffa045f490 FD: 10 BD: 8 +.+...: cx2341x:1534:(hdl)->lock

Some lock chains, that were previously causing the recursion alarms, are

The core debug code can now be simplified since all the write-only ioctls are
now const and will not modify the data they pass to the drivers.
So instead of logging write-only ioctls before the driver is called this can
now be done afterwards, which is cleaner when it comes to error reporting as
well.
This also fixes a logic error in the debugging code where there was one 'else'
too many.

The ivtv_itvc function receives a pointer to v4l2_dbg_register. When we
add const to that pointer in the s_register case we will run into a problem
here since this common function would discard const in that case. So
change this function so it receives the address and a pointer to a value.
In addition we now set the size field in the g_register function which is
where it belongs.
This will simplify the next patch where const will be added to s_register.

Previously, this has been done implicitly for video device nodes by calling
set_input() (which calls audio_input() and also modified the mute
setting).
Since input and mute setting are now untangled (as much as possible), we need to
apply the mute setting with an explicit call to audio_mute().
Also apply the mute setting when the radio device node gets opened.

it913x driver checks use of PID filter directly from DVB USB v2 core
internal variable "adap->pid_filtering" and stores it to own state.
Calling order of .pid_filter_ctrl() and .pid_filter() was changed
and due to that state was updated too late. Update state earlier.

* submit USB streaming packets
* enable HW PID filter
* ask device to start streaming
* N x add PID to device HW PID filter
... streaming video ...
* N x remove PID from device HW PID filter
* ask device to stop streaming
* disable HW PID filter
* kill USB streaming packets

when irq is serviced, a NULL pointer dereference occurs.
Also, the isr routine must be registered only if no error occurs, otherwise
the isr triggers without the proper setup, and the kernel oops again.
To prevent this, the error condition is checked, and the streamon function
exits with error. Also the isr registration call is moved after the setup

I found very small bug in xc5000 source. When set option debug=1 and
listen a radio we see in dmesg xc5000: xc_SetTVStandard()
Standard = M/N-NTSC/PAL-BTSC at all times. However, it should be, instead
"FM Radio-INPUT1_MONO".
That happens because xc5000_set_radio_freq() gets the correct value for
VideoMode and AudioMode for radio and calls xc_SetTVStandard() where name
of standard comes from the incorrect place priv->video_standard.
This incorrect debug message makes debugging a little difficult.

This seems to be ever broken. That's the status report with
Firmware 2.1, before adding support for sms2270 is:
[22273.787218] smsdvb_onresponse: MSG_SMS_GET_STATISTICS_RES
[22273.792592] IsRfLocked = 1
[22273.792592] IsDemodLocked = 1
...
[22273.792598] TransmissionMode = -64
...
(all unshown fields are filled with zeros)
Of course, transmission mode being a negative number is wrong.
So, we need to take a deeper look on it.
With the debugfs patches applied, it is possible to see that, instead
of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),
those fields are also initialized with zero:
StatisticsType = 0 FullSize = 0
IsRfLocked = 1 IsDemodLocked = 1 IsExternalLNAOn = 0
SNR = 0 dB RSSI = 0 dBm InBandPwr = 0 dBm
CarrierOffset = 0 Bandwidth = 0 Frequency = 0 Hz
TransmissionMode = -64 ModemState = 0 GuardInterval = 0
SystemType = 0 PartialReception = 0 NumOfLayers = 0
SmsToHostTxErrors = 0
The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
signal strength if StatisticsType is 0, for ISDB-T.

enum into a maximum bit number so you can safely compare the two.
So I put in two static inline translation functions instead, keeping the rest
of the code the same (except for fixing the 'gama' typo).

It turned out that some devices return less bytes then requested via i2c when
ALL of the following 3 conditions are met:
- i2c bus B is used
- there was no attempt to write to the specified slave address before
- no device present at the specified slave address
With the current code, this triggers an -EIO error and prints a message to the
system log.
Because it can happen very often during device probing, it is better to ignore
this error and bail out silently after the follwing i2c transaction success
check with -ENODEV.

Since commit 7543f344e9 ("[media] m920x:

GCC warning:
drivers/media/usb/dvb-usb/m920x.c: In function ‘m920x_probe’:
drivers/media/usb/dvb-usb/m920x.c:91:6: warning: ‘ret’ may be used uninitialized in this function [-Wuninitialized]
This warning is caused by m920x_write_seq(), which is apparently inlined
into m920x_probe(). It is clear why GCC thinks 'ret' may be used
uninitialized. But in practice the first seq->address will always be
non-zero when this function is called. That means we can change the
while()-do{} loop into a do{}-while() loop. And that suffices to make
GCC see that 'ret' will not be used uninitialized.

Similarly probe() methods should not be marked __init unless
