e99663417f [media] dm1105: release dvbnet on frontend attachment failure
The patch "dm1105: handle errors from dvb_net_init" moved the
initialization of dvbnet to before frontend attachment but forgot
to adjust the error handling when frontend attachment fails.

6c59eefd58 [media] dvb-bt8xx: convert printks to pr_err()
This module does some printks with the loglevel missing.

pr_err() takes care of adding the KERN_ERR tag and the module name.
So we can simplify the code and add the missing printk loglevel by
using it.

Also add a #define pr_fmt() to make this work, and remove a few
unnecessary periods at the end of messages and bump the loglevel of
"Unknown bttv card type" from KERN_WARNING to KERN_ERR while at it.

b247377ace [media] dvb: remove bogus modulation check
This code is wrong as I should have coded it as SYS_DVBC, instead of
SYS_DVBS & friends. Anyway, this check has other problems

1) it does some "magic" by assuming that all QAM modulations are below
  QAM_AUTO;

2) it checks modulation parameters only for one delivery system.
   Or the core should check invalid parameters for all delivery
   systems, or it should let the frontend drivers do it;

3) frontend drivers should already be checking for invalid parameters
   (most of them do it, anyway);

4) not all modulations are mapped at fe->ops.info.caps, so it is not
   even possible to check for the valid modulations inside the core
   for some delivery systems;

5) The core check is incomplete anyway: it only checks for a few
   parameters. If moved into the core other parameters like bandwidth
   and fec should also be checked;

6) 2nd gen DVB-C uses OFDM. So, that test would fail for it.

98ab8550ae [media] xc3028: fix center frequency calculation for DTV78 firmware
This patch replaces the previous one proposed in the thread "xc3028:
force reload of DTV7 firmware in VHF band with Zarlink demodulator",
at the linux-media@vger.kernel.org ML.

The problem is that the firmware DTV78 works fine in UHF band (8 MHz
bandwidth) but is not working at all in VHF band (7 MHz bandwidth).
Reading the comments inside the code, I figured out that the real
problem could be connected to the formula used to calculate the center
frequency offset in VHF band.

In fact, removing this adjustment fixes the problem:

		if ((priv->cur_fw.type & DTV78) && freq < 470000000)
			offset -= 500000;

This is coherent to what was implemented for the DTV7 firmware by an
Australian user:

		if (priv->cur_fw.type & DTV7)
			offset += 500000;

In the end, now the center frequency is the same for all firmwares
(DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth.

The final code looks clean and simple, and there is no need for any
"magic" adjustment:

		if (priv->cur_fw.type & DTV6)
			offset = 1750000;
		else	/* DTV7 or DTV8 or DTV78 */
			offset = 2750000;

5c96ebb7ce [media] videobuf-dvb: avoid spurious ENOMEM when CONFIG_DVB_NET=n
videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev
on success, but ever since commit fcc8e7d8c0 ("dvb_net: Simplify the
code if DVB NET is not defined"), ->dvbdev is left unset when
networking support is disabled.  Therefore in such configurations
videobuf_dvb_register_bus always returns failure, tripping
little-tested error handling paths and preventing the device from
being initialized and used.

Now that dvb_net_init returns a nonzero value on error, we can use
that as a more reliable error indication.  Do so.

Now your card be used with CONFIG_DVB_NET=n, and the kernel will pass
on a more useful error code describing what happened when
CONFIG_DVB_NET=y but dvb_net_init fails due to resource exhaustion.

58fae6739f [media] DVB: dvb_net_init: return -errno on error
dvb_net_init unconditionally returns 0.  Callers such as
videobuf_dvb_register_frontend examine dvbnet->dvbdev instead of the
return value to tell whether the operation succeeded.  If it has been
set to a valid pointer, success; if it was left equal to NULL,
failure.

Alas, there is an edge case where that logic does not work as well:
when network support has been compiled out (CONFIG_DVB_NET=n), we want
dvb_net_init and related operations to behave as no-ops and always
succeed, but there is no appropriate value to which to set dvb->dvbdev
to indicate this.

Let dvb_net_init return a meaningful error code, as preparation for
adapting callers to look at that instead.

The only immediate impact of this patch should be to make the few
callers that already check for an error code from dvb_net_init behave
a little more sensibly when it fails.

27351b139c [media] dw2102: use symbolic names for dw2102_table indices
dw2102_properties et al refer to entries in the USB-id table using
hard-coded indices, as in "&dw2102_table[6]", which means adding new
entries before the end of the list has the potential to introduce bugs
in code elsewhere in the file.

Use C99-style initializers with symbolic names for each index to avoid
this.  This way, other device tables wanting to reuse the USB ids can
use expressions like "&dw2102_table[TEVII_S630]" that do not change as
the entries in the table are reordered.

eabd0eaf4f [media] drivers/staging/media/as102/as102_usb_drv.c: shift position of allocation code
The conditional after the kzalloc says that the tested expression should
never be true, but if it were, the allocated data would have to be freed.
This change just moves the allocation below the test, to avoid any
possibility of the problem.

A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

// <smpl>
@r exists@
local idexpression x;
statement S;
identifier f1;
position p1,p2;

     when != if (...) { <+...x...+> }

 return \(0\|<+...x...+>\|ptr\);

527f18be2d [media] Staging: dt3155v4l: update to newer API
I changed the function definitions for dt3155_queue_setup() to match the
newer API.  The dt3155_start_streaming() function didn't do anything so
I just removed it.

This silences the following gcc warnings:

ccd1a499c1 [media] media i.MX27 camera: Fix field_count handling
To properly detect frame loss the driver must keep
track of a frame_count.

Furthermore, field_count use was erroneous because
in progressive format this must be incremented twice.

f410991dcf [media] i.MX27 camera: add support for YUV420 format
This patch uses channel 2 of the eMMa-PrP to convert
format provided by the sensor to YUV420.

This format is very useful since it is used by the
internal H.264 encoder.

48ecf9fe8f [media] soc-camera: change order of removing device
As our general practice, we use stream off before we close
the video node. So that the drivers its stream off function
would be called before its remove function.

But for the case for ctrl+c, the program would be force closed.
We have no chance to call that vb2 stream off from user space,
but directly call the remove function in soc_camera.

In that common code of soc_camera:

                ici->ops->remove(icd);
                if (ici->ops->init_videobuf2)
                        vb2_queue_release(&icd->vb2_vidq);

It would first call the device remove function, then release vb2,
in which stream off function is called. Thus it create different
order for the driver.

This patch change the order to make driver see the same sequence
to make it happy.
