Coverity complains about werid stuff at the debug logic:
CID 113542 (#1 of 1): Out-of-bounds access (ARRAY_VS_SINGLETON)10.
callee_ptr_arith: Passing buf to function flexcop_i2c_write4
which uses it as an array. This might corrupt or misinterpret
adjacent memory locations.
Instead of directly addressing the issue there, let's rework at
the logic there.
On newer kernels, KERN_CONT does nothing, as the previous message
won't wait for a continuation. Also, both flexcop_i2c_read4() and
flexcop_i2c_write4(), called by it, will print stuff if (debug &4).
So, the way it is is too buggy.
There are two kinds of debug stuff there: deb_i2c() and a code hidden
under #ifdef DUMP_I2C_MESSAGES, with can't be selected without touching
the source code.
Also, if both debug & 0x4 and DUMP_I2C_MESSAGES, flexcop_i2c_request()
will emit two debug messages per call with different data,
with sounds messy.
Simplify it by getting rid of DUMP_I2C_MESSAGES and adding a new
flag to debug (0x40), and making the debug logic there more
consistent.

Right now, at siano driver, all places where devpath is
defined has sizeof(devpath) == 32. So, there's no practical
risc of going past devpath array anywhere.
Still, code changes might cause troubles. It also confuses
Coverity:
CID 139059 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)
9. fixed_size_dest: You might overrun the 32-character
fixed-size string entry->devpath by copying devpath
without checking the length.
10. parameter_as_source: Note: This defect has an
elevated risk because the source argument
is a parameter of the current function.
So, explicitly limit strcmp() and strcpy() to ensure that the
devpath size (32) will be respected.

Some VSP instances have two blending units named BRU (Blend/ROP Unit)
and BRS (Blend/ROP Sub unit). The BRS is a smaller version of the BRU
with only two inputs, but otherwise offers similar features and offers
the same register interface. The BRU and BRS can be used exchangeably in
VSP pipelines (provided no more than two inputs are needed).
Due to historical reasons, the VSP1 driver implements support for both
the BRU and BRS through objects named vsp1_bru. The code uses the name
BRU to refer to either the BRU or the BRS, except in a few places where
noted explicitly. This creates confusion.
In an effort to avoid confusion, rename the vsp1_bru object and the
corresponding API to vsp1_brx, and use BRx to refer to blend unit
instances regardless of their type. The names BRU and BRS are retained
where reference to a particular blend unit type is needed, as well as in
hardware registers to stay close to the datasheet.

The VSPDL variant drives two DU channels through two LIF and two
blenders, BRU and BRS. The DU channels thus share the five available
VSPDL inputs and expose them as five KMS planes.
The current implementation assigns the BRS to the second LIF and thus
artificially limits the number of planes for the second display channel
to two at most.
Lift this artificial limitation by assigning the BRU and BRS to the
display pipelines on demand based on the number of planes used by each
pipeline. When a display pipeline needs more than two inputs and the BRU
is already in use by the other pipeline, this requires reconfiguring the
other pipeline to free the BRU before processing, which can result in
frame drop on both pipelines.

When disabling a DRM plane, the corresponding RPF is only marked as
removed from the pipeline in the atomic update handler, with the actual
removal happening when configuring the pipeline at atomic commit time.
This is required as the RPF has to be disabled in the hardware, which
can't be done from the atomic update handler.
The current implementation is RPF-specific. Make it independent of the
entity type by using the entity's pipe pointer to mark removal from the
pipeline. This will allow using the mechanism to remove BRU instances.

Display list completion is already reported to the frame end handler,
but that mechanism is global to all display lists. In order to implement
BRU and BRS reassignment in DRM pipelines we will need to commit a
display list and wait for its completion internally, without reporting
it to the DRM driver. Extend the display list API to support such an
internal use of the display list.

The vsp1_du_setup_lif() function sets up the DRM pipeline input
manually. This duplicates the code from the
vsp1_du_pipeline_setup_inputs() function. Replace the manual
implementation by a call to the function.
As the pipeline has no enabled input in vsp1_du_setup_lif(), the
vsp1_du_pipeline_setup_inputs() function will not setup any RPF, and
will thus not setup formats on the BRU sink pads. This isn't a problem
as all inputs are disabled, and the BRU sink pads will be reconfigured
from the atomic commit handler when inputs will be enabled.

The DRM support code manages a pipeline of VSP entities, each backed by
a media entity. When starting or stopping the pipeline, it starts and
stops the media pipeline through the media API in order to store the
pipeline pointer in every entity.
The driver doesn't use the pipe pointer in media entities, neither does
it rely on the other effects of the media_pipeline_start() and
media_pipeline_stop() functions. Furthermore, as the media links for the
DRM pipeline are never set up correctly, and as the pipeline can be
modified dynamically when enabling or disabling planes, the current
implementation is not correct. Remove the incorrect and unneeded code.
While at it remove the outdated comment that states that entities are
not started when the LIF is setup, as they now are.

Depending on the chosen standard, configure the decoder to use the
appropriate color encoding standard (PAL-like, NTSC-like or SECAM).
Until now, the decoder was not configured for a specific color standard,
making it autodetect the color encoding.
While this may sound fine, it potentially causes the wrong image tuning
parameters to be applied (e.g. tuning parameters for NTSC are applied to
a PAL source), and may confuse users about what the actual standard is
in use.
This commit explicitly configures the color standard the decoder will
use, making it visually obvious if a wrong standard was chosen.

For instance, if the user specifies V4L2_STD_PAL_60, the value actually
used will be V4L2_STD_525_60, which in the end will be as if the user
had specified V4L2_STD_NTSC, since this is always the first bitfield we

The norm_params array is only there to match a norm with an output

Check that no error happened during adding controls to the driver's
control handler. Print an error message and bail out if there was one.

Check that creating the control actually succeeded before accessing it.
A failure would lead to NULL pointer reference. Fix this.

Drivers that depend on ISAPNP currently can't be built with
COMPILE_TEST. However, looking at isapnp.h, there are already
stubs there to allow drivers to include it even when isa
PNP is not supported.
So, remove such dependencies when COMPILE_TEST.

All sound drivers that don't depend on PNP can be safelly
build with COMPILE_TEST, as ISA provides function stubs to
be used for such purposes.
As a side effect, with this change, the radio-miropcm20
can now be built outside i386 with COMPILE_TEST.
It should be noticed that ISAPNP currently depends on ISA.
So, on drivers that depend on it, we need to add an
explicit dependency on ISA, at least until another patch
removes it.

There aren't much things required for it to build with COMPILE_TEST.
It just needs to not compile the code that depends on arm-specific
iommu implementation.

The omap3isp driver can't be compiled on non-ARM platforms but has no
compile-time dependency on OMAP. It however requires common clock
framework support, which isn't provided by all ARM platforms.
Drop the OMAP dependency when COMPILE_TEST is set and add ARM and
COMMON_CLK dependencies.
