When the functions replaced media entity types, the range which was
allowed for the types was incorrect. This meant that media entity types
for specific devices were not passed correctly to the userspace through
MEDIA_IOC_ENUM_ENTITIES. Fix it.

Adds PLP ID filtering for DVB-T2.
It is untested as I don't have any signal having PLP ID other than 0.
There is only 2 extra registers, 0x32 and 0x36 on bank2, that are
programmed for DVB-T2 but not for DVB-T and all the rest are
programmed similarly - so it is likely PLP.
Pridvorov reported successfully testing it in Russia with m-PLP streams,
on both Vladivostok and Moskow.

ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.
Get rid of the union and just keep ktime_t as simple typedef of type s64.
The conversion was done with coccinelle and some manual mopping up.

With gcc-5 or higher on x86, we can get a bogus warning in the
dvb-net code:
drivers/media/dvb-core/dvb_net.c: In function 'dvb_net_ule':
arch/x86/include/asm/string_32.h:78:22: error: '*((void *)&dest_addr+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The problem here is that gcc doesn't track all of the conditions
to prove it can't end up copying uninitialized data.
This changes the logic around so we zero out the destination
address earlier when we determine that it is not set here.
This allows the compiler to figure it out.

The s_stream() handler incorrectly writes the whole MISC_CTL register to
enable or disable the outputs, overriding the output pinmuxing
configuration. Fix it to only touch the output enable bits.
The CONF_SHARED_PIN register is also written by the same function,
resulting in muxing the INTREQ signal instead of the VBLK/GPCL signal on
the INTREQ/GPCL/VBLK pin. As the driver doesn't support interrupts this
is obviously incorrect, and breaks operation on other devices. Fix it by
removing the write.

The FID/GLCO/VLK/HVLK and INTREQ/GPCL/VBLK pins are muxed differently
depending on whether the input is an S-Video or composite signal. The
comment that explains the logic doesn't reflect the code. It appears
that the comment is incorrect, as disabling the output data bus in
composite mode makes no sense. Update the comment to match the code.
While at it define macros for the MISC_CTL register bits, the code is
too confusing with numerical values.

The tvp5150 doesn't support format setting through the subdev pad API
and thus implements the set format handler as a get format operation.
The single handler, tvp5150_fill_fmt(), resets the device by calling
tvp5150_reset(). This causes malfunction as the device can be reset at
will, possibly from userspace when the subdev userspace API is enabled.
The reset call was added in commit ec2c4f3f93cb ("[media] media:
tvp5150: Add mbus_fmt callbacks"), probably as an attempt to set the
device to a known state before detecting the current TV standard.
However, the get format handler doesn't access the hardware to get the
TV standard since commit 963ddc63e20d ("[media] media: tvp5150: Add
cropping support"). There is thus no need to reset the device when
getting the format.
However, removing the tvp5150_reset() from the get/set format handlers
results in the function not being called at all if the bridge driver
doesn't use the .reset() operation. The operation is nowadays abused and
shouldn't be used, so shouldn't expect bridge drivers to call it. To
make sure the device is properly initialize, move the reset call from
the format handlers to the probe function.

commit 73d5c5c864f4 ("[media] pctv452e: don't do DMA on stack") caused
a NULL pointer dereference which occurs when dvb_usb_init()
calls dvb_usb_device_power_ctrl() for the first time, before the
frontend has been attached. It also caused a recursive deadlock because
tt3650_ci_msg_locked() has already locked the mutex.
So, partially revert it, but move the buffer to the heap
(DMA capable), not to the stack (may not be DMA capable).
Instead of sharing one buffer which needs mutex protection,
do a new heap allocation for each call.

This race was discovered by running cec-compliance -A with the cec module debug
parameter set to 2: suddenly the test would fail.
It turns out that this happens when the test configures the adapter in
non-blocking mode, then it waits for the CEC_EVENT_STATE_CHANGE event and once
the event is received it unconfigures the adapter.
What happened was that the unconfigure was executed while the configure was
still transmitting the Report Features and Report Physical Address messages.
This messed up the internal state of the cec_adapter.
The fix is to transmit those messages with the adap->lock mutex held (this will
just queue them up in the internal transmit queue, and not actually transmit
anything yet). Only unlock the mutex once everything is done. The main thread
will dequeue the messages from the internal transmit queue and transmit them
one by one, unless an unconfigure was done, and in that case any messages are
just dropped.

In the (very) small print of the REPORT_CURRENT_LATENCY message there is a
line that says that the last byte of the message (audio out delay) is only
present if the 'audio out compensated' value is 3.
I missed this, and so if this message was sent with a total length of 6 (i.e.
without the audio out delay byte), then it was rejected by the framework
since a minimum length of 7 was expected.
Fix this minimum length check and update the wrappers in cec-funcs.h to do
the right thing based on the message length.

A register used to identify chip during probe was overwritten during
firmware download and due to that later probe's for warm chip were
failing. Detect chip from the another register, which is located on
different register bank 2.

"c77d17c0 [media] lirc: use-after free" introduces two problems:
cdev_del() can be called with a NULL argument, and the kobject_put()
path will cause a double free.

Exynos5433 SoC has MFC v8 hardware module, but it has more

This patch changes the code for handling clocks. Now clocks are defined
per each device variant, what is a preparation for adding support for
Exynos 5433 MFC V8, which has more clocks than all previous versions.
Also use devm_clk_get() to simplify cleanup path.

This patch moves preparation of clocks from s5p_mfc_init_pm()
(driver probe) to s5p_mfc_power_on() (start of device operation).
This change will allow to use runtime power usage optimization
on newer Samsung Exynos platforms (for example Exynos 5433).

After commit "s5p-mfc: Fix clock management in s5p_mfc_release function"
all clocks related functions are called only when MFC device is really
available, so there is no additional check needed for NULL
gate clocks. This patch simplifies the code and kills IS_ERR_OR_NULL
macro usage.

Move clock disabling before turning power off. This will enable later
to add calls to clk_prepare/unprepare in the s5p_mfc_power_off() function
to avoid keeping clocks prepared all the time when driver is bound.

We do video allocation all the time and we need it to be fast. Plus TLB
efficiency isn't terribly important for video.
That means we want to set DMA_ATTR_ALLOC_SINGLE_PAGES.
See also the previous change (commit 14d3ae2efeed "ARM: dma-mapping: Use
DMA_ATTR_ALLOC_SINGLE_PAGES hint to optimize allocation").
[m.szyprowski: rebased patch onto v4.9-rc1 and adapted changes
to latest videbuf2 changes, this simplifies code changes to
only set proper dma attribute flag and comment the reason
for it, added commit id of arch/arm/mm patch]

Zero is not a valid value for hsv_enc. Set the field to a valid
initial value.
This is not a problem for vivid, because it sets the field to 180 via
tpg_s_hsv_enc() on the control initialization, but it might be a source
of errors for other drivers that use this code.

The cec_allocate_adapter function doesn't need the parent device, only the
cec_register_adapter function needs it.
Drop the cec_devnode parent field, since devnode.dev.parent can be used
instead.
This change makes the framework consistent with other frameworks where the
parent device is not used until the device is registered.
