f5a3048a84 media: uvcvideo: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

bed888de65 media: uvcvideo: Cleanup uvc_ctrl_add_info() error handling
There is only 1 error exit in uvc_ctrl_add_info(), so using goto style
error handling is not necessary. Also the kfree(ctrl->uvc_data) on error
is not necessary, because the only error exit is for the kzalloc() of
ctrl->uvc_data failing.

Remove all the error handling cruft and simply do "return -ENOMEM" on
kzalloc() failure.

93df48d37c media: uvcvideo: Fix uvc_ctrl_fixup_xu_info() not having any effect
uvc_ctrl_add_info() calls uvc_ctrl_get_flags() which will override
the fixed-up flags set by uvc_ctrl_fixup_xu_info().

uvc_ctrl_init_xu_ctrl() already calls uvc_ctrl_get_flags() before
calling uvc_ctrl_add_info(), so the uvc_ctrl_get_flags() call in
uvc_ctrl_add_info() is not necessary for xu ctrls.

This commit moves the uvc_ctrl_get_flags() call for normal controls
from uvc_ctrl_add_info() to uvc_ctrl_init_ctrl(), so that we no longer
call uvc_ctrl_get_flags() twice for xu controls and so that we no longer
override the fixed-up flags set by uvc_ctrl_fixup_xu_info().

This fixes the xu motor controls not working properly on a Logitech
046d:08cc, and presumably also on the other Logitech models which have
a quirk for this in the uvc_ctrl_fixup_xu_info() function.

d6834b4b58 media: uvcvideo: Set media controller entity functions
The media controller core prints a warning when an entity is registered
without a function being set. This affects the uvcvideo driver, as the
warning was added without first addressing the issue in existing
drivers. The problem is harmless, but unnecessarily worries users. Fix
it by mapping UVC entity types to MC entity functions as accurately as
possible using the existing functions.

The vivid_create_instance() function is too harry. Smatch can't

The detection part is an important piece of it. As such, there
are even comments before and after such block.

528222d853 media: rc: harmonize infrared durations to microseconds
rc-core kapi uses nanoseconds for infrared durations for receiving, and
microseconds for sending. The uapi already uses microseconds for both,
so this patch does not change the uapi.

Infrared durations do not need nanosecond resolution. IR protocols do not
have durations shorter than about 100 microseconds. Some IR hardware offers
250 microseconds resolution, which is sufficient for most protocols.
Better hardware has 50 microsecond resolution and is enough for every
protocol I am aware off.

Unify on microseconds everywhere. This simplifies the code since less
conversion between microseconds and nanoseconds needs to be done.

This affects:
 - rx_resolution member of struct rc_dev
 - timeout member of struct rc_dev
 - duration member in struct ir_raw_event

This patch fixes this by creating an exception for TT-connect S2-3650 CI

driver which makes DiSEqC/EN50494 comands which involve voltage changes
now working on the other devices (which didn't work before).

This driver still uses the USB stack for DMA transfers,
which is broken for a long time. I almost dropped this driver,
as there's a high chance that nobody is using it with upstream
Kernels, as we didn't receive any bug reports.

As fixing this won't be hard, I ended opting to fix.

While here, I dropped an ugly hack that implemented read via
a separate function that was just doing a memcpy().

It should be noticed that, during the init phase, there's
a "b4" register that were never initialized, as its buffer
were used just to store the results of "b3" initialization.

The usage of castings and float point when checking for

	drivers/media/dvb-frontends/tda10021.c:159 tda10021_set_symbolrate() warn: unsigned 'symbolrate' is never less than zero.

While the code should work with gcc, as it will evaluate the
values into a constant before compiling, other compilers
could do otherwise. So, get rid of float pointing math on it,
avoiding the need of doing typecasts.

While here, cleanup some coding style issues at the related

Sparse warns about this symbol:

	drivers/media/platform/qcom/venus/hfi_venus.c:133:5:  warning: symbol 'venus_fw_debug' was not declared. Should it be static?

Because hfi_venus.c doesn't include a header file with the

hfi_venus.c and dbgfs.c.

This way, if something changes with it, warnings or errors

importance - Venus{Low,Med,High,FW} Enabling the particular level
will be done by dynamic debug.

For example to enable debug messages with low level:
echo 'format "VenusLow" +p' > debugfs/dynamic_debug/control

If you want to enable all levels:
echo 'format "Venus" +p' > debugfs/dynamic_debug/control

All the features which dynamic debugging provide are preserved.

58084b3f6c media: venus: Fix reported frame intervals
On dragonboard-410c (apq8016) with HFI_VERSION_1XX, the reported
framerate is in unit of 1/65535 fps (for fine grained control).
So the current reported supported frame intervals is wrong (max
is 1/65535 fps), leading to encoding issues or format negotiation
failures with gstreamer.

Fix that by setting the framerate denominator to coherent value
based on the the framerate factor.

The factor is not always the same, e.g. with db820c (apq8096) HFI
reports framerate in fps unit. So only apply that for HFI_VERSION_1XX.

There are few list handling issues while adding and deleting
node in the registered buf list in the driver.
1. list addition - buffer added into the list during buf_init
while not deleted during cleanup.
2. list deletion - In capture streamoff, the list was reinitialized.
As a result, if any node was present in the list, it would
lead to issue while cleaning up that node during buf_cleanup.

d935856317 media: uapi: h264: Clean slice invariants syntax elements
The H.264 specification requires in section 7.4.3 "Slice header semantics",
that the following values shall be the same in all slice headers:

  pic_parameter_set_id
  frame_num
  field_pic_flag
  bottom_field_flag
  idr_pic_id
  pic_order_cnt_lsb
  delta_pic_order_cnt_bottom
  delta_pic_order_cnt[ 0 ]
  delta_pic_order_cnt[ 1 ]
  sp_for_switch_flag
  slice_group_change_cycle

These bitstream fields are part of the slice header, and therefore
passed redundantly on each slice. The purpose of the redundancy
is to make the codec fault-tolerant in network scenarios.

This is of course not needed to be reflected in the V4L2 controls,
given the bitstream has already been parsed by applications.
Therefore, move the redundant fields to the per-frame decode
parameters control (DECODE_PARAMS).

Field 'pic_parameter_set_id' is simply removed in this case,
because the PPS control must currently contain the active PPS.

Syntax elements dec_ref_pic_marking() and those related
to pic order count, remain invariant as well, and therefore,
the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size
are also common to all slices.
