media: mceusb: return without resubmitting URB in case of -EPROTO error.
Syzkaller reported a warning called "rcu detected stall in dummy_timer".
The error seems to be an error in mceusb_dev_recv(). In the case of
-EPROTO error, the routine immediately resubmits the URB. Instead it
should return without resubmitting URB.

media: mxl111sf: change mutex_init() location
Syzbot reported, that mxl111sf_ctrl_msg() uses uninitialized
mutex. The problem was in wrong mutex_init() location.
Previous mutex_init(&state->msg_lock) call was in ->init() function, but
dvb_usbv2_init() has this order of calls:
dvb_usbv2_init()
dvb_usbv2_adapter_init()
dvb_usbv2_adapter_frontend_init()
props->frontend_attach()
props->init()
Since mxl111sf_* devices call mxl111sf_ctrl_msg() in ->frontend_attach()
internally we need to initialize state->msg_lock before
frontend_attach(). To achieve it, ->probe() call added to all mxl111sf_*
devices, which will simply initiaize mutex.

media: atmel: fix the ispck initialization
The runtime enabling of the ISPCK (internally clocks the pipeline inside
the ISC) has to be done after the pm_runtime for the ISC dev has been
started.
After the commit by Mauro:
the ISC failed to probe with the error:
atmel-sama5d2-isc
f0008000.isc: failed to enable ispck: -13
atmel-sama5d2-isc: probe of
f0008000.isc failed with error -13
This is because the enabling of the ispck is done too early in the probe,
and the PM runtime returns invalid request.
Thus, moved this clock enabling after pm_runtime_idle is called.
The ISPCK is required only for sama5d2 type of ISC.
Thus, add a bool inside the isc struct that is platform dependent.
For the sama7g5-isc, the enabling of the ISPCK is wrong and does not make
sense. Removed it from the sama7g5 probe. In sama7g5-isc, there is only
one clock, the MCK, which also clocks the internal pipeline of the ISC.
Adapted the clk_prepare and clk_unprepare to request the runtime PM
for both clocks (MCK and ISPCK) in case of sama5d2-isc, and the single
clock (MCK) in case of sama7g5-isc.

media: rcar-vin: Use user provided buffers when starting
When adding an internal scratch buffer to improve buffer handling when
stopping it was also erroneously used when syncing at capture start.
This led to that the first three buffers captured were always dropped
as they were captured in the scratch buffer instead of in a buffer
provided by the user.
Allow the hardware to be given user provided buffers when preparing for
capture in the stopped state. This still allows the driver to sync with
the hardware and always completes the buffers to user-space in the
correct order as no buffers are completed before the sync is complete.
This change improves the driver as buffers are completed and given to
the user three frames earlier than before.

media: video-i2c: more precise intervals between frames
MLX90640 should ideally be working without a frame skip.
In short, if a frame is skipped, then half of a frame loses correction
information, having no way to retrieve its original compensation.
This patch improves the timing in three ways:
1) Replaced schedule_timeout_interruptible() to usleep_range()
The former "only ensures that it will sleep for at least
schedule_delay (if not interrupted)", as pointed out by mchehab.
As a result, the frame rate could lag behind than the actual capability
of the hardware
(Raspberry Pi would show a few Hz slower than set value)
2) Calculation based on us, not jiffies
Jiffies usually has resolution of 100Hz, and possibly even cruder.
MLX90640 can go up to 64Hz frame rate, which does not make sense to
calculate the interval with aforementioned resolution.
3) Interval calculation based on the last frame's end time
Using the start time of the current frame will probably make tiny bit
of drift every time. This made more sense when I didn't realize 1),
but it still makes sense without adding virtually any complexity,
so this stays in.

media: videobuf2: rework vb2_mem_ops API
With the new DMA API we need an extension of the videobuf2 API.
Previously, videobuf2 core would set the non-coherent DMA bit
in the vb2_queue dma_attr field (if user-space would pass a
corresponding memory hint); the vb2 core then would pass the
vb2_queue dma_attrs to the vb2 allocators. The vb2 allocator
would use the queue's dma_attr and the DMA API would allocate
either coherent or non-coherent memory.
But we cannot do this anymore, since there is no corresponding DMA
attr flag and, hence, there is no way for the allocator to become
aware of what type of allocation user-space has requested. So we
need to pass more context from videobuf2 core to the allocators.
Fix this by changing the call_ptr_memop() macro to pass the
vb2 pointer to the corresponding op callbacks.

media: cec-pin: fix off-by-one SFT check
The CEC pin framework has to wait for the CEC bus to be idle for the
requested Signal Free Time before it can start a transmit.
However, the check for that was off by one, so transmits would start one
bit period (2.4ms) too late.

media: s5p-mfc: fix possible null-pointer dereference in s5p_mfc_probe()
The variable pdev is assigned to dev->plat_dev, and dev->plat_dev is
checked in:
if (!dev->plat_dev)
This indicates both dev->plat_dev and pdev can be NULL. If so, the
function dev_err() is called to print error information.
dev_err(&pdev->dev, "No platform data specified\n");
However, &pdev->dev is an illegal address, and it is dereferenced in
dev_err().
To fix this possible null-pointer dereference, replace dev_err() with
mfc_err().

media: aspeed-video: ignore interrupts that aren't enabled
As partially addressed in commit
65d270acb2d6 ("media: aspeed: clear
garbage interrupts"), the ASpeed video engine sometimes asserts
interrupts that the driver hasn't enabled. In addition to the
CAPTURE_COMPLETE and FRAME_COMPLETE interrupts dealt with in that
patch, COMP_READY has also been observed. Instead of playing
whack-a-mole with each one individually, we can instead just blanket
ignore everything we haven't explicitly enabled.

media: firewire: firedtv-avc: fix a buffer overflow in avc_ca_pmt()
The bounds checking in avc_ca_pmt() is not strict enough. It should
be checking "read_pos + 4" because it's reading 5 bytes. If the
"es_info_length" is non-zero then it reads a 6th byte so there needs to
be an additional check for that.
I also added checks for the "write_pos". I don't think these are
required because "read_pos" and "write_pos" are tied together so
checking one ought to be enough. But they make the code easier to
understand for me. The check on write_pos is:
if (write_pos + 4 >= sizeof(c->operand) - 4) {
The first "+ 4" is because we're writing 5 bytes and the last " - 4"
is to leave space for the CRC.
The other problem is that "length" can be invalid. It comes from
"data_length" in fdtv_ca_pmt().
