commit 1b976fc6d684e3282914cdbe7a8d68fdce19095c upstream.
The driver needs an isochronous endpoint to be present. It will
oops in its absence. Add checking for it.

commit 8c279e9394cade640ed86ec6c6645a0e7df5e0b6 upstream.
When parsing the UVC control descriptors fails, the error path tries to
cleanup a media device that hasn't been initialised, potentially
resulting in a crash. Fix this by initialising the media device before
the error handling path can be reached.

commit 9e08117c9d4efc1e1bc6fce83dab856d9fd284b6 upstream.
Visual inspection of the usbvision driver shows that it suffers from
three races between its open, close, and disconnect handlers. In
particular, the driver is careful to update its usbvision->user and
usbvision->remove_pending flags while holding the private mutex, but:
usbvision_v4l2_close() and usbvision_radio_close() don't hold
the mutex while they check the value of
usbvision->remove_pending;
usbvision_disconnect() doesn't hold the mutex while checking
the value of usbvision->user; and
also, usbvision_v4l2_open() and usbvision_radio_open() don't
check whether the device has been unplugged before allowing
the user to open the device files.
Each of these can potentially lead to usbvision_release() being called
twice and use-after-free errors.
This patch fixes the races by reading the flags while the mutex is
still held and checking for pending removes before allowing an open to
succeed.

commit c7a191464078262bf799136317c95824e26a222b upstream.
The syzbot fuzzer found two invalid-access bugs in the usbvision
driver. These bugs occur when userspace keeps the device file open
after the device has been disconnected and usbvision_disconnect() has
set usbvision->dev to NULL:
When the device file is closed, usbvision_radio_close() tries
to issue a usb_set_interface() call, passing the NULL pointer
as its first argument.
If userspace performs a querycap ioctl call, vidioc_querycap()
calls usb_make_path() with the same NULL pointer.
This patch fixes the problems by making the appropriate tests
beforehand. Note that vidioc_querycap() is protected by
usbvision->v4l2_lock, acquired in a higher layer of the V4L2
subsystem.

commit 30045f2174aab7fb4db7a9cf902d0aa6c75856a7 upstream.
Since commit c2b71462d294 ("USB: core: Fix bug caused by duplicate
interface PM usage counter") USB drivers must always balance their
runtime PM gets and puts, including when the driver has already been
unbound from the interface.
Leaving the interface with a positive PM usage counter would prevent a
later bound driver from suspending the device.
Note that runtime PM has never actually been enabled for this driver
since the support_autosuspend flag in its usb_driver struct is not set.

commit 14e3cdbb00a885eedc95c0cf8eda8fe28d26d6b4 upstream.
A bugfix introduce a link failure in configurations without CONFIG_MODULES:
In file included from drivers/media/usb/dvb-usb/pctv452e.c:20:0:
drivers/media/usb/dvb-usb/pctv452e.c: In function 'pctv452e_frontend_attach':
drivers/media/dvb-frontends/stb0899_drv.h:151:36: error: weak declaration of 'stb0899_attach' being applied to a already existing, static definition
The problem is that the !IS_REACHABLE() declaration of stb0899_attach()
is a 'static inline' definition that clashes with the weak definition.
I further observed that the bugfix was only done for one of the five users
of stb0899_attach(), the other four still have the problem. This reverts
the bugfix and instead addresses the problem by not dropping the reference
count when calling '->detach()', instead we call this function directly
in dvb_frontend_put() before dropping the kref on the front-end.
I first submitted this in early 2018, and after some discussion it
was apparently discarded. While there is a long-term plan in place,
that plan is obviously not nearing completion yet, and the current
kernel is still broken unless this patch is applied.

[ Upstream commit 4843a543fad3bf8221cf14e5d5f32d15cee89e84 ]
If reg_r() fails, then gspca_dev->usb_buf was left uninitialized,
and some drivers used the contents of that buffer in logic.
This caused several syzbot errors:

I analyzed the gspca drivers and zeroed the buffer where needed.

[ Upstream commit 765bb8610d305ee488b35d07e2a04ae52fb2df9c ]
When CONFIG_DVB_DIB9000 is disabled, we can still compile code that
now fails to link against dibx000_i2c_set_speed:
drivers/media/usb/dvb-usb/dib0700_devices.o: In function `dib01x0_pmu_update.constprop.7':
dib0700_devices.c:(.text.unlikely+0x1c9c): undefined reference to `dibx000_i2c_set_speed'
The call sites are both through dib01x0_pmu_update(), which gets passed
an 'i2c' pointer from dib9000_get_i2c_master(), which has returned
NULL. Checking this pointer seems to be a good idea anyway, and it avoids
the link failure in most cases.
Sean Young found another case that is not fixed by that, where certain
gcc versions leave an unused function in place that causes the link error,
but adding an explict IS_ENABLED() check also solves this.

Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc"

This driver has three locking issues:
- The wait_event_interruptible() condition calls hdpvr_get_next_buffer(dev)
which uses a mutex, which is not allowed. Rewrite with list_empty_careful()
that doesn't need locking.
- In hdpvr_read() the call to hdpvr_stop_streaming() didn't lock io_mutex,
but it should have since stop_streaming expects that.
- In hdpvr_device_release() io_mutex was locked when calling flush_work(),
but there it shouldn't take that mutex since the work done by flush_work()
also wants to lock that mutex.
There are also two other changes (suggested by Keith):
- msecs_to_jiffies(4000); (a NOP) should have been msleep(4000).
- Change v4l2_dbg to v4l2_info to always log if streaming had to be restarted.

The conversion here is really trivial: just a bunch of title
markups and very few puntual changes is enough to make it to
be parsed by Sphinx and generate a nice html.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

creation of the second and following debugfs directories will fail and
print an info message like this:
"uvcvideo: Unable to create debugfs 3-2 directory."

As this driver had a major change, let's take the opportunity
and do some coding style cleanup, in order to make it compliant
with Kernel's style.
This patch was partially done with the help of two tools:
./scripts/checkpatch.pl --fix-inplace --strict
astyle --indent=tab=8 --style=linux
But manually adjusted in order to fit our style.
