Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.
But this only really works if all drivers use this, so convert
all radio drivers in this patch.

Support for multiplanar and singleplanar formats is mutually exclusive,
at least in practice. In our attempt to unify support for support for
mplane and !mplane in v4l, let's get rid of the
->vidioc_enum_fmt_{vid,out}_cap_mplane() hooks and call
->vidioc_enum_fmt_{vid,out}_cap() instead.

This is needed if we want the core to be able to check _MPLANE support
without having to call the ->vidioc_querycap() hook.

With fast_io enabled, spinlock_irq is used for read/write operations,
thus leading to :

The variable err is assigned with a value that is never read and
it is re-assigned a new value later on. The assignment is redundant

This patch fixes a coccinelle warning and includes ktime.h instead of
timekeeping.h. The first includes the latter, but the latter doesn't
exist before 3.17, causing problems for our compat build. It's easier
to just use ktime.h instead.

The main changes are:
1) misc verifier improvements, from Alexei.
2) bpftool can now convert btf to valid C, from Andrii.
3) verifier can insert explicit ZEXT insn when requested by 32-bit JITs.
This feature greatly improves BPF speed on 32-bit architectures. From Jiong.
4) cgroups will now auto-detach bpf programs. This fixes issue of thousands
bpf programs got stuck in dying cgroups. From Roman.
5) new bpf_send_signal() helper, from Yonghong.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on

devm functions are fine for managing resources that are directly related
to the device at hand and that have no other dependencies. However, a
process holding a file handle to a device created by a driver for a device
may result in the file handle left behind after the device is long gone.
This will result in accessing released (and potentially reallocated)
memory.
Instead, manage the memory resources in the driver. Releasing the
resources can be later on bound to e.g. by releasing a reference.

The A83T SoC has a camera sensor interface (known as CSI in Allwinner

In vb2_vmalloc_get_userptr() the framevector is created with the
'write' argument set to false when vb2_create_framevec() is called
for OUTPUT buffers. So the pages are marked as read-only.
However, userspace will write to these buffers since it will fill
in the data to output. Since get_userptr is only called if the userptr
of the queued buffer has changed since the last time that same buffer
was queued, this will fail when the buffer contents is updated and the
buffer is queued again.
E.g., userspace fills buffer 1 with the output video and queues it.
The first time get_userptr is called and the pages are grabbed and
pinned in memory and marked read-only. The second time buffer 1 is
filled with different video data and queued again. Since the userptr
hasn't changed the get_userptr() callback isn't called again. Since
the pages were marked as read-only the new contents isn't updated.
Just always call vb2_create_framevec() with FOLL_WRITE to always
allow writing to the buffers.
Using USERPTR streaming with OUTPUT devices is almost never done. And
when it is done it is via v4l2-compliance and a driver like vim2m. But
since v4l2-compliance doesn't actually inspect the capture buffer and
compare it to the original output buffer, this issue was never noticed.
But the vicodec driver actually needs to parse the bitstream in the
OUTPUT buffers and any errors there will be immediately noticed. So
this time v4l2-compliance failed the USERPTR streaming test.
