The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
This is similar to commit 64b92de9603f
("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put")
In the error handling path, the clk_prepare_enable() function
call should be balanced by a corresponding 'clk_disable_unprepare()'
call , as already done in the remove function.
The TX clock source may be changed in next case, need to
disable it when stop, otherwise the TX may not work after
changing the clock source, error log is:
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]
are not NULL, it will cause leaks.
of_node_put() will check if the node pointer is NULL, so we can
call it directly to release the refcount of regular pointers.
Fix the missing clk_disable_unprepare() before return
from rk817_platform_probe() in the error handling case.

The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was
returned).
The root cause was the introduction of the caps field in ivtv-driver.h.
While loading the ivtvfb module would update the video_device device_caps
field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps
field, and that's what the overlay ioctls would look at.
It's a bad idea to keep information in two places, so drop the caps field
and only use vdev.device_caps.

There is one call trace that snd_soc_register_card()
->snd_soc_bind_card()->soc_init_pcm_runtime()
->snd_soc_dai_compress_new()->snd_soc_new_compress().
In the trace the 'codec_dai' transfers from card->dai_link,
and we can see from the snd_soc_add_pcm_runtime() in
snd_soc_bind_card() that, if value of card->dai_link->num_codecs
is 0, then 'codec_dai' could be null pointer caused
by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'.
And snd_soc_register_card() is called by various platforms.
Therefore, it is better to add the check in the case of misusing.
And because 'cpu_dai' has already checked in soc_init_pcm_runtime(),
there is no need to check again.
Adding the check as follow, then if 'codec_dai' is null,
snd_soc_new_compress() will not pass through the check
'if (playback + capture != 1)', avoiding the leftover use of
'codec_dai'.

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

double buffer size in comparison to older Cedrus core generations.

lead to NULL pointer dereference on failure of devm_kzalloc().
Fix this bug by adding a NULL check of ctx->active_fmt.
This bug was found by a static analyzer.
Builds with 'make allyesconfig' show no new warnings, and our static
analyzer no longer warns about this code.

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).
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.

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.

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.

The Hantro H1 hardware can crop off pixels from the right and bottom of
the source frame. These are controlled with the H1_REG_IN_IMG_CTRL_OVRFLB

The ChromeOS kernel driver that this was based on incorrectly added the
_D4 suffix H1_REG_IN_IMG_CTRL_OVRFLB. This field crops the bottom of the
input frame, and the number is _not_ divided by 4. [1]
Correct the name to avoid confusion when crop support with the selection
API is added.

Therefore, it should be better to check it in order to avoid the

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

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

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

DST_QUEUE_OFF_BASE is applied to offset/mem_offset on MMAP capture buffers
only for the VIDIOC_QUERYBUF ioctl, while the userspace fields (including
offset/mem_offset) are filled in for VIDIOC_{QUERY,PREPARE,Q,DQ}BUF
ioctls. This leads to differences in the values presented to userspace.
If userspace attempts to mmap the capture buffer directly using values
from DQBUF, it will fail.
Move the code that applies the magic offset into a helper, and call
that helper from all four ioctl entry points.

When multiple CSIS instances are present in a single graph, they are
currently all named "imx7-mipi-csis.0", which breaks the entity name
uniqueness requirement. Fix it by using the device name to create the
subdev name.
