[ Upstream commit a97b693c3712f040c5802f32b2d685352e08cefa ]
These two architectures implement 8-byte get_user() through
a memcpy() into a four-byte variable, which won't fit.
Use a temporary 64-bit variable instead here, and use a double
cast the way that risc-v and openrisc do to avoid compile-time
warnings.

In ov5640_set_fmt, pending_fmt_change will always be false, because the
sensor format is saved before comparing it with the previous format:
fmt = &sensor->fmt;...
*fmt = *mbus_fmt;...
if (mbus_fmt->code != sensor->fmt.code)
sensor->pending_fmt_change = true;
This causes the sensor to capture with the previous pixelcode.
Also, changes might happen even for V4L2_SUBDEV_FORMAT_TRY, so fix that.
Basically, revert back to the state before
commit 071154499193 ("media: ov5640: Fix set format regression")
as it was more clear, and then update format even when pixelcode does
not change, as resolution might change.

In the final H264 API, it is not required to set scaling matrix if
they are not present in the bitstream. A flag was added in order to let
the driver know. The downside is that it leaves the default control
value to 0, which isn't valid. As per the spec (see formulas 7-8/7-9),
when the scaling matrix are absent from the bitstream, flat values
of 16 should be used. This improves this control semantic in a way
that the control value are always valid. Drivers can then use
the scaling_matrix control values without having to check its presence.
Same method was employed for MPEG2_QUANTISATION.
This fixes issues with MTK VCODEC H264 decoder when using GStreamer.
GStreamer does not set this control if its not present in the bitstream.
As MTK VDCODEC was using the initialized to 0 values, the frames ended
up completely gray.

Quoting the header comments, IRQF_ONESHOT is "Used by threaded interrupts
which need to keep the irq line disabled until the threaded handler has
been run.". When applied to an interrupt that doesn't request a threaded
irq then IRQF_ONESHOT has a lesser known (undocumented?) side effect,
which it to disable the forced threading of the irq. For "normal" kernels
(without forced threading) then, if there is no thread_fn, then
IRQF_ONESHOT is a nop.
In this case disabling forced threading is not appropriate for this driver
because it calls wake_up_all() and this API cannot be called from
no-thread interrupt handlers on PREEMPT_RT systems (deadlock risk, triggers
sleeping-while-atomic warnings).
Fix this by removing IRQF_ONESHOT.

be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the

This code has two bugs:
1) "cnt" is 255 but the size of the buffer is 256 so the last byte is
not used.
2) If we try to print more than 255 characters then "cnt" will be
negative and that will trigger a WARN() in snprintf(). The fix for
this is to use scnprintf() instead of snprintf().
We can re-write this code to be cleaner:
1) Rename "offset" to "off" because that's shorter.
2) Get rid of the "cnt" variable and just use "size - off" directly.
3) Get rid of the "read" variable and just increment "off" directly.

[ Upstream commit 1f6f1e959a85ee999fbc86f4b094827f63194c7f ]
According to subdevice interface specification found in V4L2 API
documentation, set format pad operations should not affect image
geometry set in preceding image processing steps. Unfortunately, that
requirement is not respected by the driver implementation of set format
as it was not the case when that code was still implementing a pair of
now obsolete .s_mbus_fmt() / .try_mbus_fmt() video operations before
they have been merged and reused as an implementation of .set_fmt() pad
operation by commit 717fd5b4907a ("[media] v4l2: replace try_mbus_fmt
by set_fmt").
In case of set format active processing path the issue can be fixed
easily by excluding a call to set active selection from that path. That
will effectively limit frame size processing to optimal frame scaling
against active crop rectangle without touching it. Users can just call
set active selection themselves to obtain desired frame size. However,
set format try processing path needs more work.
First of all, the driver should be extended with set try selection
support. Lack of it constraints video device drivers to not use
subdevice cropping at all while processing user requested active frame
size, otherwise their set try format results might differ from active.
Next, set format try processing path should use pad config crop
rectangle as a reference, not the active one as it does now. That
issue can be resolved easily as soon as set try selection support is
added to the driver so pad config crop rectangle can be maintained by
users via selection API.
Last, set format try processing path should give the same results as
active in respect to active vs. pad config crop rectangle geometry.
Both rectangles should be either not touched by set format (that's what
we are going to achieve) or modified the same way, otherwise users
won't be able to obtain equal results from both paths while iterating
through set format and set selection operations in order to obtain
desired frame size.
We can't begin with modifying set format pad operation as not to touch
crop rectangle since that depends on availability of set try selection
for symmetry. Neither can we begin with adding set try selection since
that in turn depends on equal handling of active and pad config crop
rectangles by set format. We can either implement all required
modifications in a single patch, or begin with fixing current set
format try processing path to appropriately handle pad config crop
rectangle. This patch implements the latter approach as believed to
be more readable.
Move crop rectangle adjustments code from a helper (the former
implementation of .s_fmt(), now called from set format active
processing path) to the body of set format pad operation function
where it can be also used for processing try requests for symmetry with
active ones. As the helper no longer processes frame geometry, only
frame format and half scaling, simplify its API accordingly and update
its users.
Moreover, extract code that applies crop rectangle hardware limits
(now a part of .set_selection() operation which is called from set
format active processing path) to a new helper and call that helper
from set format try processing path as well for symmetry with active.

If an mclk-fs value was provided in the device tree configuration, the

however set_sysclk was not being called on the platform device. Some

as well.
Call snd_soc_component_set_sysclk on each component in the stream to set
the proper sysclk value in addition to the existing call of
snd_soc_dai_set_sysclk on the codec DAI and CPU DAI. This may end up
resulting in redundant calls if one of the snd_soc_dai_set_sysclk calls
ends up calling snd_soc_component_set_sysclk itself, but that isn't
expected to cause any significant harm.
