Markus Elfring 045d69ce21 [media] cx88-dsp: Use kmalloc_array() in read_rds_samples()
* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kmalloc_array".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data type by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

Andrey Utkin 6dfcd29657 [media] tw5864: crop picture width to 704
Previously, width of 720 was used, but it gives 16-pixel wide black bar
at right side of encoded picture.

Wei Yongjun e546b1ef22 [media] cx88: fix error return code in cx8802_dvb_probe()
Fix to return error code -ENODEV from the error handling case
instead of 0(err maybe overwrited to 0 in the for loop), as
done elsewhere in this function.

[mchehab@s-opensource.com: remove a now uneeded set for err = -ENODEV]

Mauro Carvalho Chehab db6d8d5fdf [media] tw68: 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.

</script>
use Text::Tabs;
while (<>) {
	if ($next ne "") {
		$c=$_;
		if ($c =~ /^\s+\"(.*)/) {
			$c2=$1;
			$next =~ s/\"\n$//;
			$n = expand($next);
			$funpos = index($n, '(');
			$pos = index($c2, '",');
			if ($funpos && $pos > 0) {
				$s1 = substr $c2, 0, $pos + 2;
				$s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2;

Mauro Carvalho Chehab 652fd6eaeb [media] bt8xx: 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.

Mauro Carvalho Chehab 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.

This removes the 'write' and 'force' use from get_user_pages_unlocked()
and replaces them with 'gup_flags' to make the use of FOLL_FORCE
explicit in callers as use of this flag can result in surprising
behaviour (and hence bugs) within the mm subsystem.

This commit removes explicit includes except the following:

Petr Mladek 3989144f86 kthread: kthread worker API cleanup
A good practice is to prefix the names of functions by the name
of the subsystem.

The kthread worker API is a mix of classic kthreads and workqueues.  Each
worker has a dedicated kthread.  It runs a generic function that process
queued works.  It is implemented as part of the kthread subsystem.

This patch renames the existing kthread worker API to use
the corresponding name from the workqueues API prefixed by
kthread_:

__init_kthread_worker()		-> __kthread_init_worker()
init_kthread_worker()		-> kthread_init_worker()
init_kthread_work()		-> kthread_init_work()
insert_kthread_work()		-> kthread_insert_work()
queue_kthread_work()		-> kthread_queue_work()
flush_kthread_work()		-> kthread_flush_work()
flush_kthread_worker()		-> kthread_flush_worker()

Note that the names of DEFINE_KTHREAD_WORK*() macros stay
as they are. It is common that the "DEFINE_" prefix has
precedence over the subsystem names.

Note that INIT() macros and init() functions use different
naming scheme. There is no good solution. There are several
reasons for this solution:

  + "init" in the function names stands for the verb "initialize"
    aka "initialize worker". While "INIT" in the macro names
    stands for the noun "INITIALIZER" aka "worker initializer".

  + INIT() macros are used only in DEFINE() macros

  + init() functions are used close to the other kthread()
    functions. It looks much better if all the functions
    use the same scheme.

  + There will be also kthread_destroy_worker() that will
    be used close to kthread_cancel_work(). It is related
    to the init() function. Again it looks better if all
    functions use the same naming scheme.

  + there are several precedents for such init() function
    names, e.g. amd_iommu_init_device(), free_area_init_node(),
    jump_label_init_type(),  regmap_init_mmio_clk(),

  + It is not an argument but it was inconsistent even before.

Bhaktipriya Shridhar 072973ba67 [media] cx25821: Remove deprecated create_singlethread_workqueue
The workqueue "_irq_audio_queues" runs the audio upstream handler.
It has a single work item(&dev->_audio_work_entry) and hence doesn't
require ordering. Also, it is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

The work item has been flushed in cx25821_stop_upstream_audio() to ensure
that nothing is pending when the driver is disconnected.

Andrey Utkin 350649cc24 [media] tw5864-core: remove excessive irqsave
As warned by smatch:
	drivers/media/pci/tw5864/tw5864-core.c:160 tw5864_h264_isr() error: double lock 'irqsave:flags'
	drivers/media/pci/tw5864/tw5864-core.c:174 tw5864_h264_isr() error: double unlock 'irqsave:flags'

Two different spinlocks are obtained, so having two calls is correct,
but second irqsave is superfluous, and using same "flags" variable is
just wrong.

Ezequiel Garcia f8afaa8dbc [media] tw686x: Introduce an interface to support multiple DMA modes
Let's set the corner stone to support all the DMA modes
available on this device.

For stability reasons, the driver is currently setting DMA frame
mode, and using single DMA buffers to get the P and B buffers.
Each frame is then memcpy'ed into the user buffer.

However, other platforms might be interested in avoiding this
memcpy, or in taking advantage of the chip's DMA scatter-gather
capabilities.

To achieve this, this commit introduces a "dma_mode" module parameter,
and a tw686x_dma_ops struct. This will allow to define functions to
alloc/free DMA buffers, and to return the frames to userspace.

The memcpy-based method described above is named as dma_mode="memcpy".
Current alloc/free functions are renamed as tw686x_memcpy_xxx,
and are now used through a memcpy_dma_ops.

support. When compiled with modules disabled, this is now
producing this bogus warning:

drivers/media/pci/cx25821/cx25821-alsa.c:696:35: warning: 'cx25821_audio_pci_tbl' defined but not used [-Wunused-const-variable=]

                                   ^~~~~~~~~~~~~~~~~~~~~

Fix it by annotating that the function may not be used.

In this specific case, this is somewhat intentional, as those
values are actually used in parts of the driver. The code assumes
that gcc optimizer it and not actually create any var, but convert
it to immediate access at the routines.

Yet, as we want to shut up gcc warnings, let's use #define, with
is the standard way to store values that will use assembler's
immediate access code.

Mauro Carvalho Chehab 363d79f1d5 [media] tw686x: Don't go past array
Depending on the compiler version, currently it produces the

	tw686x-video.c: In function 'tw686x_video_init':
	tw686x-video.c:65:543: warning: array subscript is above array bounds [-Warray-bounds]

This is actually bogus with the current code, as it currently
hardcodes the framerate to 30 frames/sec, however a potential
use after the array size could happen when the driver adds support
for setting the framerate. So, fix it.

Hans Verkuil 7b9f31f3b3 [media] sta2x11_vip: fix s_std
The s_std ioctl was broken in this driver, partially due to the
changes to the adv7180 driver (this affected the handling of
V4L2_STD_ALL) and partially because the new standard was never
stored in vip->std.

The handling of V4L2_STD_ALL has been rewritten to just call querystd
and the new standard is now stored correctly.
