Pull media fixes from Mauro Carvalho Chehab:
"Media regression fixes:
- serial_ir: fix a Kernel crash during boot on Kernel 4.11-rc1, due
to an IRQ code called too early
- other IR regression fixes at lirc and at the raw IR decoding
- a deadlock fix at the RC nuvoton driver
- fix another issue with DMA on stack at dw2102 driver
There's an extra patch there that change a driver interface for the
SoC VSP1 driver, with is shared between the DRM and V4L2 driver. The
patch itself is trivial, and was acked by David Arlie"

The interface to configure the LIF in the VSP1 requires adapting the
function prototype for any changes. This makes extending the interface
difficult.
Change the function prototype to pass a structure which can be easily
extended.
This changes the means of disabling the pipeline, by now passing a NULL
configuration rather than passing either a 0 width or height.
[Fixed kerneldoc, made vsp1_du_setup_lif() cfg argument const]

Drivers might try to access and run enable_source and disable_source
handlers when the driver that implements these handlers is clearing
the handlers during its unregister.
Fix the following race condition:
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(doesn't hold graph_mutex)
mdev->enable_source = NULL;
if (mdev && mdev->enable_source) mdev->disable_source = NULL;
mdev->enable_source()
(enable_source holds graph_mutex)
As shown above enable_source check is done without holding the graph_mutex.
If unbind happens to be in progress, au0828 could clear enable_source and
disable_source handlers leading to null pointer de-reference.
Fix it by protecting enable_source and disable_source set and clear and
protecting enable_source and disable_source handler access and the call
itself.
process 1 process 2
request video streaming unbind au0828
v4l2 checks if tuner is free
... ...
au0828_unregister_media_device()
... ...
(hold graph_mutex while clearing)
mdev->enable_source = NULL;
if (mdev) mdev->disable_source = NULL;
(hold graph_mutex to check and
call enable_source)
if (mdev->enable_source)
mdev->enable_source()
If graph_mutex is held to just heck for handler being null and needs to be
released before calling the handler, there will be another window for the
handlers to be cleared. Hence, enable_source and disable_source handlers
no longer hold the graph_mutex and expect callers to hold it to avoid
forcing them release the graph_mutex before calling the handlers.

IR raw transmitter driver type is specified in the enum
rc_driver_type as RC_DRIVER_IR_RAW_TX which includes all those
devices that transmit raw stream of bit to a receiver.
The data are provided by userspace applications, therefore they
don't need any input device allocation, but still they need to be
registered as raw devices.

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.
This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.
Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true and
rc_dev::allowed_wakeup_protocols should be set to the raw IR encoders.
We also do not permit the mask to be set as we cannot generate IR
which would match that.

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.
In addition, we need to know the specific variant of the protocol.
In short, these changes are made to the wakeup_protocols sysfs entry:
- list all the protocol variants rather than the protocol groups,
e.g. "nec nec-x nec-32" rather than just "nec".
- only allow one protocol variant to be selected rather than multiple
- wakeup_filter can only be set once a protocol has been selected in
wakeup_protocols.
This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.
As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.
Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.
The patch has been generated using the following command:
git grep -l media_entity |xargs perl -i -pe '
s/media_entity_pipeline/media_pipeline/g;
s/media_entity_graph/media_graph/g'
And a few manual edits related to line start alignment and line wrapping.

Currently, there's a mess at the V4L2 printk macros: some drivers
use their own macros, others use pr_foo() or v4l_foo() macros,
while more modern drivers use dev_foo() macros.
The best is to get rid of v4l_foo() macros, as they can be
replaced by either dev_foo() or pr_foo(). Yet, such change can
be disruptive, as dev_foo() cannot use KERN_CONT. So, the best
is to do such change driver by driver.
There are replacements for most v4l_foo() macros, but it lacks
a way to enable debug messages per level. So, add such macro,
in order to make the conversion easier.

rc_register_device
Introduce managed versions of both functions.
They allows to simplify the error path in the probe function of
rc drivers, and usually also to simplify the remove function.
New element managed_alloc in struct rc_dev is needed to correctly
handle mixed use, e.g. managed version of rc_register_device and
normal version of rc_allocate_device.
In addition devm_rc_allocate_device sets rc->dev.parent as having a
reference to the parent device might be useful for future extensions.

Currently we do not know what variant (bit length) of the nec protocol
is used, other than from guessing from the length of the scancode. Now
nec will be handled the same way as the sony protocol or the rc6 protocol;
one variant per bit length.

and we don't want to be introducing this world of pain into userspace
too.

The rcar_fcp_enable() function immediately returns successfully when the
FCP device pointer is NULL to avoid forcing the users to check the FCP
device manually before every call. However, the stub version of the
function used when the FCP driver is disabled returns -ENOSYS
unconditionally, resulting in a different API contract for the two
versions of the function.
As a user that requires FCP support will fail at probe time when calling
rcar_fcp_get() if the FCP driver is disabled, the stub version of the
rcar_fcp_enable() function will only be called with a NULL FCP device.
We can thus return 0 unconditionally to align the behaviour with the
normal version of the function.

Fix this warning:
Documentation/media/kapi/mc-core.rst:97: WARNING: c:func reference target not found: media_devnode_release
The media_device_release() is a function internal to media-devnode.c,
and not exported elsewhere. So, we can't cross-reference it here.
Make it explicit at the documentation.
