That are due to the usage of printf-like messages without
enabling the error checking logic.
Add the proper attributes in order to shut up such warnings.

Gcc reports that input_formatter_alignment is not used:
In file included from ./drivers/staging/media/atomisp//pci/hive_isp_css_include/input_formatter.h:34,
from drivers/staging/media/atomisp//pci/runtime/debug/src/ia_css_debug.c:55:
./drivers/staging/media/atomisp//pci/hive_isp_css_common/host/input_formatter_local.h:118:27: warning: ‘input_formatter_alignment’ defined but not used [-Wunused-const-variable=]
However, it is, but only inside input_formatter.c.
So, move it out of the header file.

ia_css_vf_configure() logic has an error var that detects troubles
when setting the kernel for downscaling. The driver just ignores
it, without producing any warning. Add at least a warning message
on such cases.

The code that used to check for ISP2400/2401 version were
using the revision number in order to decide wheather
version should be used. With the new version, the code
doesn't need to check anymore for ISP version.

In order to reduce even further the size of the big
vivid_create_instance() function, let's place the part of the
logic which creates the device nodes into a separate function.
With this and the past patches, those warnings finally
vanishes:
drivers/media/test-drivers/vivid/vivid-core.c: drivers/media/test-drivers/vivid/vivid-core.c:1189 vivid_create_instance() parse error: turning off implications after 60 seconds
drivers/media/test-drivers/vivid/vivid-core.c: drivers/media/test-drivers/vivid/vivid-core.c:1257 vivid_create_instance() parse error: __split_smt: function too hairy. Giving up after 303 seconds
The init code also seems more organized after breaking the long
function into a smaller set.

The vivid_create_instance() is still a too big for my taste.

The vivid_create_instance() function is too harry. Smatch can't
process it, because it takes too long.
The detection part is an important piece of it. As such, there
are even comments before and after such block.
So, it makes sense to just move it to a separate function.

rc-core kapi uses nanoseconds for infrared durations for receiving, and
microseconds for sending. The uapi already uses microseconds for both,
so this patch does not change the uapi.
Infrared durations do not need nanosecond resolution. IR protocols do not
have durations shorter than about 100 microseconds. Some IR hardware offers
250 microseconds resolution, which is sufficient for most protocols.
Better hardware has 50 microsecond resolution and is enough for every
protocol I am aware off.
Unify on microseconds everywhere. This simplifies the code since less
conversion between microseconds and nanoseconds needs to be done.
This affects:
- rx_resolution member of struct rc_dev
- timeout member of struct rc_dev
- duration member in struct ir_raw_event

Both TT-connect S2-3600 and Pinnacle PCTV Sat HDTV are using
Intersil ISL6423 as LNB voltage regulator. This makes
TT-connect S2-3650 CI the only device which uses STM LNBP22 regulator
which is currently used for all devices driven by pctv452e driver.
This patch fixes this by creating an exception for TT-connect S2-3650 CI
to continue to use STM LNBP22 while all others now using correct ISL6423
driver which makes DiSEqC/EN50494 comands which involve voltage changes
now working on the other devices (which didn't work before).

As there aren't duplicated names anymore, and the end goal

remove the part of the Makefile which changes the include
places based on the compile-time version.

for further patches meant to remove conditional compiler
decisions between ISP versions to be replaced by
runtime ones.

As reported by smatch:
drivers/media/pci/saa7134//saa7134-tvaudio.c:686 saa_dsp_writel() warn: should 'reg << 2' be a 64 bit type?
On a 64-bits Kernel, the shift might be bigger than 32 bits.
In real, this should never happen, but let's shut up the warning.

Instead of calling printk(), use pr_foo() macros.
While here, do some cleanup at the printed messages, as some
has __func__, while others have the module name (sometimes
spelled as "ttusb_dvb").

This driver still uses the USB stack for DMA transfers,
which is broken for a long time. I almost dropped this driver,
as there's a high chance that nobody is using it with upstream
Kernels, as we didn't receive any bug reports.
As fixing this won't be hard, I ended opting to fix.
While here, I dropped an ugly hack that implemented read via
a separate function that was just doing a memcpy().
It should be noticed that, during the init phase, there's
a "b4" register that were never initialized, as its buffer
were used just to store the results of "b3" initialization.

The usage of castings and float point when checking for
the setup based at the symbol_rate cause those warnings
with smatch:
drivers/media/dvb-frontends/tda10021.c:153 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
drivers/media/dvb-frontends/tda10021.c:155 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
drivers/media/dvb-frontends/tda10021.c:157 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
drivers/media/dvb-frontends/tda10021.c:159 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.
While the code should work with gcc, as it will evaluate the
values into a constant before compiling, other compilers
could do otherwise. So, get rid of float pointing math on it,
avoiding the need of doing typecasts.
While here, cleanup some coding style issues at the related
code.

Sparse warns about this symbol:
drivers/media/platform/qcom/venus/hfi_venus.c:133:5: warning: symbol 'venus_fw_debug' was not declared. Should it be static?
Because hfi_venus.c doesn't include a header file with the
extern. So, move it to core.h, with is included by both
hfi_venus.c and dbgfs.c.
This way, if something changes with it, warnings or errors
will be produced.

While smatch reports an issue there:

drivers/media/pci/ttpci/av7110_v4l.c:165 ves1820_set_tv_freq() warn: unsigned 'freq' is never less than zero.
The logic is actually fine. Yet, removing the typecast
shuts up smatch and makes the code more readable.

As pointed by smatch:
drivers/media/tuners/qt1010.c:239 qt1010_init_meas1() error: uninitialized symbol 'val2'.
drivers/media/tuners/qt1010.c:273 qt1010_init_meas2() error: uninitialized symbol 'val'.
The logic is ok, but it is hard for static analyzers
to parse it, as it depends on a value read in the middle
of a loop.
Also, it takes a while for humans to verify.
Re-write the first function to use a more direct way.
At the second one, I opted to just initialize the read var,
in order to shut up the report.
While here, address a few coding style issues at the
function code.

The original logic had an integer to unsigned integer
conversion, plus a float-point math. While gcc should be
able to do the match at compile time, other compilers might
not do the same. Also, those produce the following warnings

Upon running Sparse, "warning: dubious: !x | !y" is brought to notice
for this file. Logical and bitwise OR are basically the same in this
context, so it doesn't cause a runtime bug. But let's change it to
logical OR to make it a little bit cleaner and silence the Sparse
warning.
