This reverts 8b0e195314fa, because media-tree drivers should use the
API functions to initialize variables of type ktime_t.

Such check is already there at the routine. So, no need to
repeat it outside.

Except for DVB, all media kAPI headers are at include/media.
Move the headers to it.

When a user starts and stops filtering at a demux device too quickly
in a very short interval, the user process hangs in uninterruptible sleep,
due to an inconsistency of kthread status in the driver.
The kthread can be stopped before it starts running its thread function,
but the invocation status was partly managed in the kthread function,
which resulted in a double kthread_stop() of one kthread.

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.

As warned by smatch:
drivers/media/pci/pt3/pt3.c:398 pt3_attach_fe() error: strncmp() '"tc90522sat"' too small (11 vs 20)
Clearly, the logic is doing the wrong thing, as it is not comparing the strings
on the right way.

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.
So, let's do it.
This patch was generated by this shell script:
for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done
While here, make CodingStyle fixes on the affected lines.

Use dev_err instead of pt1_printk
o reduce object code size
o remove now unused pt1_printk macro
Neaten dev_<level> uses in pt3
o add missing newlines
o align arguments
o remove unnecessary OOM messages as there's a generic one
o typo fixes in messages

Get rid of 'module_is_live' usage.
on x86_64:
when CONFIG_MODULES is not enabled:
../drivers/media/pci/pt3/pt3.c: In function 'pt3_attach_fe':

This patch adds support for PT3 PCIe cards.
PT3 has an FPGA PCIe bridge chip, a TC90522 demod chip and
a VA4M6JC2103 tuner module which contains two QM1D1C0042 chips for ISDB-S
and two MxL301RF's for ISDB-T.
It can receive and deliver 4 (2x ISDB-S, 2x ISDB-T) streams simultaneously,
and a kthread is used per stream to poll incoming data,
because PT3 does not have interrupts.
As an antenna input for each delivery system is split in the tuner module
and shared between the corresponding two tuner chips,
LNB/LNA controls that the FPGA chip provides are (naturally) shared as well.
The tuner chips also share the power line in the tuner module,
which is controlled on/off by a GPIO pin of the demod chip.
As with the demod chip and the ISDB-T tuner chip,
the init sequences/register settings for those chips are not disclosed
and stored in a private memory of the FPGA,
PT3 driver executes the init of those chips on behalf of their drivers.
