5cbe9f3acf [media] ivtv: fix two smatch warnings
Smatch currently produces two warnings:
	drivers/media/pci/ivtv/ivtv-fileops.c:901 ivtv_v4l2_close() warn: suspicious bitop condition
	drivers/media/pci/ivtv/ivtv-fileops.c:1026 ivtv_open() warn: suspicious bitop condition

Those are false positives, but it is not hard to get rid of them by
using a different way to evaluate the macro, splitting the logical
boolean evaluation from the bitmap one.

c65171cf6f [media] bt8xx: remove needless check
As reported by smatch:
	drivers/media/pci/bt8xx/dst_ca.c:323 ca_get_message() warn: this array is probably non-NULL. 'p_ca_message->msg'
	drivers/media/pci/bt8xx/dst_ca.c:498 ca_send_message() warn: this array is probably non-NULL. 'p_ca_message->msg'

Those two checks are needless/useless, as the ca_msg struct is
declared as:
typedef struct ca_msg {
        unsigned int index;
        unsigned int type;
        unsigned int length;
        unsigned char msg[256];
} ca_msg_t;

So, if the p_ca_message pointer is not null, msg will also be
not null.

3725d53149 [media] ivtv: fix incorrect audio mode report in log_status
The log_status ioctl should report if the audio input has mode Bilingual. However, the
check against the itv->dualwatch_stereo_mode is completely wrong and is a left-over from
the distant past. Not only is the bitmask obviously wrong, the test itself is broken too
since itv->dualwatch_stereo_mode is no longer a bitmask at all.

Fix this code properly.

86bad00a2f [media] cobalt: fix irqs used for the adv7511 transmitter
The interrupt bit assignments use for the adv7511 were off by one.
This means that the current scheme (bit << (4 * stream_index)) can
no longer be used.

Fix this by precalculating and storing the correct masks in the
cobalt_stream struct.

This wasn't noticed before because the adv7511 interrupts are very
rare. But for CEC support these interrupts are essential, so this made
me realize that it wasn't working correctly.

85756a069c [media] cobalt: add new driver
The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a
connector that can be used to hook up an adv7511 transmitter or an
adv7842 receiver daughterboard.

This device is used within Cisco but is sadly not available outside
of Cisco. Nevertheless it is a very interesting driver that can serve
as an example of how to support HDMI hardware and how to use the popular
adv devices.

Enhances driver to use an MSI interrupt when available.

Adds the module option 'enable_msi' (type bool) which by default is
enabled. Can be set to 'N' to disable.

Fixes (or can reduce the occurrence of) a crash which is most commonly
reported when both digital tuners of the saa7164 chip is in use. A
reported example can be found here:

6be5b1a19a [media] saa7134: change the debug macros for IR input
Rename the macros to input_dbg() and ir_dbg(), using pr_fmt()
on both, to be coherent with the other debug macro changes.

The ir_dbg() also prints the IR name.

I'm not sure if it is a good idea to keep both macros here,
but merging them would require tests on different flavors of
saaa7134-based boards.

So, for now, let's keep both.

30693f346e [media] saa7134-i2c: make debug macros to use pr_fmt()
Converting debug prints to use pr_foo() is not trivial, as the
result will be a way worse than what's provided here, due to the
pieces of the code that prints the I2C transfers. Those use a
lot pr_cont(), and, depending on using either level 1 or 2,
a different set of macros are selected.

So, let's replace d1printk() and d2printk() macros by i2c_dbg()
and i2c_count() adding a debug level there.

c6c62cce32 [media] saa7134: better handle core debug messages
On media drivers, debugging messages should be grouped into
categories, as this makes easier to debug the driver.

In the case of saa7134, the core has 2 debug categories, one
for IRQ, and another one for the core itself. The IRQ have
actually 2 levels of debug.

So, instead of using pr_dbg(), where everything would be in
the same box, let's define two macros that use pr_fmt(),
one for the core, and another one for irq.

With that, we can replace the remaining printk() occurrences
at the core to use either core_dbg() or irq_dbg(), depending
on the group of debug macros that need to be enabled.

As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
