The s5p-cec driver returned CEC_TX_STATUS_ERROR for the NACK condition.
Some digging into the datasheet uncovered the S5P_CEC_TX_STAT1 register where
bit 0 indicates if the transmit was nacked or not.
Use this to return the correct CEC_TX_STATUS_NACK status to userspace.
This was the only driver that couldn't tell a NACK from another error, and
that was very unusual. And a potential problem for applications as well.
Tested with my Odroid-U3.

Pull media updates from Mauro Carvalho Chehab:
"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

Implements g_/s_selection crop support by using DCMI crop
hardware feature.
User can first get the maximum supported resolution of the sensor
by calling g_selection(V4L2_SEL_TGT_CROP_BOUNDS).
Then user call to s_selection(V4L2_SEL_TGT_CROP) will reset sensor
to its maximum resolution and crop request is saved for later usage
in s_fmt().
Next call to s_fmt() will check if sensor can do frame size request
with crop request. If sensor supports only discrete frame sizes,
the frame size which is larger than user request is selected in
order to be able to match the crop request. Then s_fmt() resolution
user request is adjusted to match crop request resolution.

The configuration of the pipeline and entities directly affects the
inputs required to each entity for the partition algorithm. Thus it
makes sense to involve those entities in the decision making process.
Extend the entity ops API to provide an optional .partition() operation.
This allows entities that affect the partition window to adapt the
window based on their configuration.
Entities implementing this operation must update the window parameter in
place, which will then be passed up the pipeline. This creates a process
whereby each entity describes what is required to satisfy the required
output to its predecessor in the pipeline.
