c558d13c21 [media] em28xx: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.

As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.

So, join those continuation lines.

The patch was generated via the script below, and manually
adjusted if needed.

this won't work as expected anymore. So, let's add KERN_CONT

b676e7316a [media] dvb-core: move dvb_filter out of the DVB core
The dvb_filter.c can hardly be considered as part of the DVB
core. More than half of the code there is commented out by
av7110 and ttusb_dec.

On the latter, just two small helper functions and a struct
definition is used.

Being part of the core means that it would require an
amount of work to fix issues in it, like bad printk's
on it, and to document it on some future, like other kAPI
headers. It simply not worth the effort for something that
seems to be deprecated, as no new drivers use it.

So, move it out of the core, by moving it to pci/ttpci
directory, where av7110 driver is kept, and copy the two
routines used by ttyusb_dec directly into its code.

ab883e2de3 [media] dtt200u: don't do DMA on stack
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.

Be sure that I2C reads won't use stack by passing
a pointer to the state buffer, that we know it was

allocated by an I2C client.

c2730eef5f [media] cinergyT2-fe: cache stats at cinergyt2_fe_read_status()
Instead of sending USB commands for every stats call, collect
them once, when status is updated. As the frontend kthread
will call it on every few seconds, the stats will still be
collected.

Besides reducing the amount of USB/I2C transfers, this also
warrants that all stats will be collected at the same time,
and makes easier to convert it to DVBv5 stats in the future.

97139d4a6f treewide: remove redundant #include <linux/kconfig.h>
Kernel source files need not include <linux/kconfig.h> explicitly
because the top Makefile forces to include it with:

  -include $(srctree)/include/linux/kconfig.h

This commit removes explicit includes except the following:

  * arch/s390/include/asm/facilities_src.h
  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

3cc2691227 [media] ttusb_dec: avoid the risk of go past buffer
Fixes this smatch warning:
	drivers/media/usb/ttusb-dec/ttusb_dec.c:243 ttusb_dec_handle_irq() error: buffer overflow 'rc_keys' 26 <= 126

As the RC keys should be enabled previously, via:
	set_bit(rc_keys[i], input_dev->keybit);

It wouldn't go past the buffer in practice. Yet, as bad
things may happen when going past buffer, it doesn't hurt adding
a check here.

While here, fix CodingStyle issues on the routine.
