This change is a redesign in the formats and the way the ISC is
configured w.r.t. sensor format and the output format from the ISC.
I have changed the splitting between sensor output (which is also ISC input)
and ISC output.
The sensor format represents the way the sensor is configured, and what ISC
is receiving.
The format configuration represents the way ISC is interpreting the data and
formatting the output to the subsystem.
Now it's much easier to figure out what is the ISC configuration for input, and
what is the configuration for output.
The non-raw format can be obtained directly from sensor or it can be done
inside the ISC. The controller format list will include a configuration for
each format.
The old supported formats are still in place, if we want to dump the sensor
format directly to the output, the try format routine will detect and
configure the pipeline accordingly.
This also fixes the previous issues when the raw format was NULL which
resulted in many crashes for sensors which did not have the expected/tested
formats.

Add following V4L2 QP parameters for H.264:
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_I_FRAME_MAX_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MIN_QP
* V4L2_CID_MPEG_VIDEO_H264_P_FRAME_MAX_QP
These controls will limit QP range for intra and inter frame,
provide more manual control to improve video encode quality.

commit f1a2e44a3aec ("bpf: add queue and stack maps") introduced new BPF
helper functions:
- BPF_FUNC_map_push_elem
- BPF_FUNC_map_pop_elem
- BPF_FUNC_map_peek_elem
but they were made available only for network BPF programs. This patch
makes them available for tracepoint, cgroup and lirc programs.

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

The exposure control is clustered with the autoexposure control and
flagged as volatile, but the g_volatile_ctrl() doesn't handle
V4L2_CID_EXPOSURE_AUTO. So, the value of the exposure control can't be
read in autoexposure mode.
This enables to get the exposure control in autoexposure mode by making
ov7740_get_volatile_ctrl() deal with V4L2_CID_EXPOSURE_AUTO.
This also sets the exposure control as volatile by specifying the
argument to v4l2_ctrl_auto_cluster() instead of manually flagging it.

Smatch marks skb->data as untrusted so it warns that "evt_hdr->dlen"
can copy up to 255 bytes and we only have room for two bytes. Even
if this comes from the firmware and we trust it, the new policy
generally is just to fix it as kernel hardenning.
I can't test this code so I tried to be very conservative. I considered
not allowing "evt_hdr->dlen == 1" because it doesn't initialize the
whole variable but in the end I decided to allow it and manually
initialized "asic_id" and "asic_ver" to zero.

Commit 0650a91499e0 ("media: mtk-vcodec: Correct return type for mem2mem
buffer helpers") fixed the return types for mem2mem buffer helper
functions by changing a few local variables from vb2_buffer to
vb2_v4l2_buffer. However, it left a few accesses to vb2_buffer::planes
as-is, accidentally turning them into accesses to
vb2_v4l2_buffer::planes and resulting in values being read from/written
to the wrong place.
Fix this by inserting vb2_buf into these accesses so they mimic their
original behavior.

clang warns about a possible variable use that gcc never
complained about:
drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
[-Werror,-Wuninitialized]
dm365_vpss_set_pg_frame_size(frame_size);
^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
struct vpss_pg_frame_size frame_size;
^
1 error generated.
There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.
On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.
To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

Smatch warns about small size on two structs:
drivers/media/platform/qcom/venus/hfi_parser.c:103 parse_profile_level() error: memcpy() 'proflevel' too small (8 vs 128)
drivers/media/platform/qcom/venus/hfi_parser.c: drivers/media/platform/qcom/venus/hfi_parser.c:129 parse_caps() error: memcpy() 'cap' too small (16 vs 512)
The reason is that the hfi_parser actually expects:
- multiple data entries on hfi_capabilities
- multiple profile_level on hfi_profile_level_supported
However, the structs trick gcc, making it to believe that
there's just one value for each.

The only way for p_set to be NULL would be if vin_coef_set would be an
empty array.
On such case, the driver will OOPS, as it would try to de-reference a
NULL value. So, the check if p_set is not NULL doesn't make any sense.
Solves those two smatch warnings:
drivers/media/platform/rcar-vin/rcar-dma.c:489 rvin_set_coeff() warn: variable dereferenced before check 'p_set' (see line 484)

There are some macros at cx2341x_update() with seemed to
be introduced in order to ensure that lines would be less
than 80 columns.
Well, the thing is that they make the code harder to be analized,
not only by humans, but also for static code analyzers:
drivers/media/common/cx2341x.c:1116 cx2341x_update() error: we previously assumed 'old' could be null (see line 1047)
So, remove the "force" var, and replace the NEQ macro to a
better designed one that makes clearer about what it is doing.
While here, also remove the "temporal" var, as it is just another
way of doing the same type of check as the new CMP_FIELD() macro
already does.
Finally, fix coding style at the block code.
remove such macros.

As warned by smatch:
drivers/media/i2c/imx214.c:591 imx214_set_format() warn: variable dereferenced before check 'format' (see line 589)
It turns that the code at imx214_set_format() has support for being
called with the format being NULL. I've no idea why, as it is only
called internally with the pointer set, and via subdev API (with
should also set it).
Also, the entire logic there depends on having format != NULL, so
just remove the bogus broken support for a null format.

If requests are used when they shouldn't, or not used when they should,
then return EBADR (Invalid request descriptor) instead of EACCES.
The reason for this change is that EACCES has more to do with permissions
(not being the owner of the resource), but in this case the request file
descriptor is just wrong for the current mode of the device.

Stateless codecs require the use of the Request API as opposed of it
being optional.
So add a bit to indicate this and let vb2 check for this.
If an attempt is made to queue a buffer without an associated request,
then the EBADR error is returned to userspace.
Doing this check in the vb2 core simplifies drivers, since they
don't have to check for this, they can just set this flag.
