Move `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating
internal buffers. Previously, the buffer was enqueued in `buffers->list`
before the DMA allocation. If the allocation failed, the function returned
`-ENOMEM` while leaving a partially initialized buffer in the list, which
could lead to inconsistent state and potential leaks.
By adding the buffer to the list only after `dma_alloc_attrs()` succeeds,
we ensure the list contains only valid, fully initialized buffers.

Two platform-data fields for SM8750 were missed:
- get_vpu_buffer_size = iris_vpu33_buf_size
Without this, the driver fails to allocate the required internal
buffers, leading to basic decode/encode failures during session
bring-up.
- max_core_mbps = ((7680 * 4320) / 256) * 60
Without this capability exposed, capability checks are incomplete and
v4l2-compliance for encoder fails.

handling
Currently v4l2_m2m_ioctl_{de,enc}coder_cmd is being invoked during STOP
command handling. However, this is not required as the iris driver has
its own drain and stop handling mechanism in place.
Using the m2m command API in this context leads to incorrect behavior,
where the LAST flag is prematurely attached to a capture buffer,
when there are no buffers in m2m source queue. But, in this scenario
even though the source buffers are returned to client, hardware might
still need to process the pending capture buffers.
Attaching LAST flag prematurely can result in the capture buffer being
removed from the destination queue before the hardware has finished
processing it, causing issues when the buffer is eventually returned by
the hardware.
To prevent this, remove the m2m API usage in stop handling.

According to 4.5.1.5 of the M2M stateful decoder UAPI documentation,
providing the width and the height to S_FMT is "required only if it
cannot be parsed from the stream", otherwise they can be left as 0
and the S_FMT implementation is expected to return a valid placeholder
resolution that would let REQBUFS succeed.
iris was missing the fallback, so clients like rpi-ffmpeg wouldn't work.
Fix by adding an explicit fallback to defaults.

iris_venc_s_param() uses do_div to divide two 64 bits operators, this is
wrong. Luckily for us, both of the operators fit in 32 bits, so we can use
a normal division.
Now that we are at it, mark the fps smaller than 1 as invalid, the code
does not seem to handle them properly.
The following cocci warning is fixed with this patch:

When the ffmpeg decoder is running, the driver receives the
V4L2_BUF_FLAG_KEYFRAME flag in the input buffer. The driver then forwards
this flag information to the firmware. The firmware, in turn, copies the
input buffer flags directly into the output buffer flags. Upon receiving
the output buffer from the firmware, the driver observes that the buffer
contains the HFI_BUFFERFLAG_DATACORRUPT flag. The root cause is that both
V4L2_BUF_FLAG_KEYFRAME and HFI_BUFFERFLAG_DATACORRUPT are the same value.
As a result, the driver incorrectly interprets the output frame as
corrupted, even though the frame is actually valid. This misinterpretation
causes the driver to report an error and skip good frames, leading to
missing frames in the final video output and triggering ffmpeg's "corrupt
decoded frame" error.
To resolve this issue, the input buffer flags should not be sent to the
firmware during decoding, since the firmware does not require this
information.

This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4.
Revert the check that skipped stop_streaming when the instance was in
IRIS_INST_ERROR, as it caused multiple regressions:
1. Buffers were not returned to vb2 when the instance was already in
error state, triggering warnings in the vb2 core because buffer
completion was skipped.
2. If a session failed early (e.g. unsupported configuration), the
instance transitioned to IRIS_INST_ERROR. When userspace attempted
to stop streaming for cleanup, stop_streaming was skipped due to the
added check, preventing proper teardown and leaving the firmware
in an inconsistent state.

On SM8250 (IRIS2) with firmware older than 1.0.087, the firmware could
not handle a dummy device address for EOS buffers, so a NULL device
address is sent instead. The existing check used IS_V6() alongside a
firmware version gate:
if (IS_V6(core) && is_fw_rev_or_older(core, 1, 0, 87))
fdata.device_addr = 0;
else
fdata.device_addr = 0xdeadb000;
However, SC7280 which is also V6, uses a firmware string of the form
"1.0.<commit-hash>", which the version parser translates to 1.0.0. This
unintentionally satisfies the `is_fw_rev_or_older(..., 1, 0, 87)`
condition on SC7280. Combined with IS_V6() matching there as well, the
quirk is incorrectly applied to SC7280, causing VP9 decode failures.
Constrain the check to IRIS2 (SM8250) only, which is the only platform
that needed this quirk, by replacing IS_V6() with IS_IRIS2(). This
restores correct behavior on SC7280 (no forced NULL EOS buffer address).

When hfi_session_flush is issued, all queued buffers are returned to
the V4L2 driver. Some of these buffers are not processed and have
bytesused = 0. Currently, the driver marks such buffers as error even
during drain operations, which can incorrectly flag EOS buffers.
Only capture buffers with zero payload (and not EOS) should be marked
with VB2_BUF_STATE_ERROR. The check is performed inside the non-EOS
branch to ensure correct handling.

Even if a video device is part of a pipeline already,
video_device_pipeline_alloc_start() handles that case gracefully. Don't
explicitly differentiate between video_device_pipeline_start() and
video_device_pipeline_alloc_start() based on the existence of a pipeline.

Obtain unique source pad from a remote sub-device, instead of the first
one. This means that only one link may be active at stream start. There's
no functional change in practice, unless multiple CSI-2 transmitters are
directly connected to the receiver.

There's no reason to use media_entity_remote_source_pad_unique() as we
know our pads. Use media_pad_remote_pad_unique() instead.
