The last argument of v4l2_ctrl_add_handler() indicates whether the controls
you add are from a control handler owned by another driver (true) or from
the same driver (false). In this case the last argument was incorrectly set
to false. The controls come from the cx25840 subdev.

The dma_q->p_left_data alloced by kzalloc should be freed in all the
following error handling paths. However, it hasn't been freed in the
allocation error paths of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer.
On the other hand, the dma_q->p_left_data did be freed in the
error-handling paths after that of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer, by calling
cx231xx_uninit_isoc(dev). So the same free operation should be done in
error-handling paths of those two allocation.

cx231xx_close_extension and hence cx231xx_audio_fini() are called with the
cx231xx device lock held, but snd_cx231xx_pcm_close() also grabs that mutex
when closing the file on behalf of arecord. There seems to be no reason to
wait for sound card resources to be released, so let the release be
asynchronous.
Tested with a Hauppauge 955Q (2040:b123) and Linux 5.9.6; the hang
described in the bug no longer occurs and disconnecting the device
correctly terminates arecord with ENODEV.

list_for_each_entry is able to handle an empty list.
The only effect of avoiding the loop is not initializing the
index variable.
Drop list_empty tests in cases where these variables are not
used.
Note that list_for_each_entry is defined in terms of list_first_entry,
which indicates that it should not be used on an empty list. But in
list_for_each_entry, the element obtained by list_first_entry is not
really accessed, only the address of its list_head field is compared
to the address of the list head, so the list_first_entry is safe.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
<smpl>
@@
expression x,e;
iterator name list_for_each_entry;
statement S;
identifier i;

The boards listed below use i2c device drivers and have
tuner_type equal TUNER_ABSENT. This means additional support
is required to enable the analog tuning capability, a case
statement is used to identify these models.

- CX231XX_BOARD_HAUPPAUGE_975 (tested)
- CX231XX_BOARD_EVROMEDIA_FULL_HYBRID_FULLHD (untested)

Right now, if one has an hybrid TV card, it has to select
both analog and digital TV support, as otherwise the needed
core support won't be selected.
Change the logic to auto-select the core support for those
drivers, as this is a way more intuitive.
It should be noticed that, as now both DVB_CORE and VIDEO_DEV
defaults depends on selecting a hybrid cards, we had to remove
the explicit dependencies there, in order to avoid circular
dependencies.
That requires some tricks:
1) the prompt should not be not visible when an hybrid card
is selected, as the user shold not change it.
2) When a media hybrid device is selected, the modular
option for DVB_CORE and VIDEO_DEV will follow the
MEDIA_SUPPORT dependency, as we can't have a core
built with "y" with a driver built as module.
Note: while here, moved two pure V4L2 PCI drivers out of the
"hybrid" part of config and consider pvrusb2 as an hybrid
device.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6

Pull new experimental media request API from Mauro Carvalho Chehab:
"A new media request API
This API is needed to support device drivers that can dynamically
change their parameters for each new frame. The latest versions of
Google camera and codec HAL depends on such feature.
At this stage, it supports only stateless codecs.
It has been discussed for a long time (at least over the last 3-4
years), and we finally reached to something that seem to work.
This series contain both the API and core changes required to support
it and a new m2m decoder driver (cedrus).
As the current API is still experimental, the only real driver using
it (cedrus) was added at staging[1]. We intend to keep it there for a
while, in order to test the API. Only when we're sure that this API
works for other cases (like encoders), we'll move this driver out of
staging and set the API into a stone.
[1] We added support for the vivid virtual driver (used only for
testing) to it too, as it makes easier to test the API for the ones
that don't have the cedrus hardware"

Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set. Fix this by casting value[3] to a u32 before
the shift.
Detected by CoverityScan, CID#1016522 ("Unintended sign extension")
