In mtk_jpegdec_worker, if error occurs in mtk_jpeg_set_dec_dst, it
will start the timeout worker and invoke v4l2_m2m_job_finish at
the same time. This will break the logic of design for there should
be only one function to call v4l2_m2m_job_finish. But now the timeout
handler and mtk_jpegdec_worker will both invoke it.
Fix it by start the worker only if mtk_jpeg_set_dec_dst successfully
finished.

mtk_jpeg_dec_device_run
In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with
mtk_jpeg_job_timeout_work.
In mtk_jpeg_dec_device_run, if error happens in
mtk_jpeg_set_dec_dst, it will finally start the worker while
mark the job as finished by invoking v4l2_m2m_job_finish.
There are two methods to trigger the bug. If we remove the
module, it which will call mtk_jpeg_remove to make cleanup.
The possible sequence is as follows, which will cause a
use-after-free bug.
CPU0 CPU1
mtk_jpeg_dec_... |
start worker |
|mtk_jpeg_job_timeout_work
mtk_jpeg_remove |
v4l2_m2m_release |
kfree(m2m_dev); |
|
| v4l2_m2m_get_curr_priv
| m2m_dev->curr_ctx //use
If we close the file descriptor, which will call mtk_jpeg_release,
it will have a similar sequence.
Fix this bug by starting timeout worker only if started jpegdec worker
successfully. Then v4l2_m2m_job_finish will only be called in
either mtk_jpeg_job_timeout_work or mtk_jpeg_dec_device_run.

of multi-core JPEG devices
This patch reverts commit c677d7ae8314
("media: mtk-jpeg: Fix use after free bug due to uncanceled work").
The job_timeout_work is initialized only for
the single-core JPEG device so it will cause the crash for multi-core
JPEG devices.
Fix it by removing the cancel_delayed_work_sync function.

buffers array
Use vb2_get_buffer() instead of direct access to the vb2_queue bufs array.
This allows us to change the type of the bufs in the future.
After each call to vb2_get_buffer() we need to be sure that we get
a valid pointer so check the return value of all of them.

The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.
Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.

Pull media updates from Mauro Carvalho Chehab:
- new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913
- new Intel IVSC MEI drivers
- some Mediatek platform drivers were moved to a common location
- Intel atomisp2 driver is now working with the main ov2680 driver. Due
to that, the atomisp2 ov2680 staging one was removed
- the bttv driver was finally converted to videobuf2 framework. This
was the last one upstream using videobuf version 1 core. We'll likely
remove the old videobuf framework on 6.7
- lots of improvements at atomisp driver: it now works with normal I2C
sensors. Several compile-mode dependecies to select between ISP2400
and ISP2401 are now solved in runtime
- a new ipu-bridge logic was added to work with IVSC MEI drivers
- venus driver gained better support for new VPU versions
- the v4l core async framework has gained lots of improvements and
cleanups
- lots of other cleanups, improvements and driver fixes

In the multi-core JPEG encoder/decoder setup, the driver for the
individual cores references the parent device's platform driver data.
However, in the parent driver, this is only set at the end of the probe
function, way later than devm_of_platform_populate(), which triggers
the probe of the cores. This causes a kernel splat in the sub-device
probe function.
Move platform_set_drvdata() to before devm_of_platform_populate() to
fix this.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The mtk8195_jpegenc_drvdata object was added outside of an #ifdef causing
a harmless build warning.
drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable]
1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = {
| ^~~~~~~~~~~~~~~~~~~~~~~
A follow-up patch moved it inside of an #ifdef, which caused more
warnings, and a third patch ended up adding even more #ifdefs. These
were all bogus, since the actual problem here is the incorrect use
of of_ptr(). Since the driver (like any other modern platform driver)
only works in combination with CONFIG_OF, there is no point in hiding
the reference, so just remove that along with all the pointless #ifdef
checks in the driver.
This improves build coverage and avoids running into the same problem
again when another part of the driver gets changed that relies on
the #ifdef blocks to be completely matched.

"RST" is indeed a name too short to be conflict-free.
Fix this by creating a common <media/jpeg.h> header file, containing
definitions for all JPEG markers used, prefixed by "JPEG_MARKER_", based
on the existing private definitions in the Samsung S5P JPEG driver, and
convert all affected drivers.

In order to simplify the masters to set their respective dma masks, MTK
IOMMU helps to centralize the processing. Because all the dma ranges is

dma-ranges/dma_mask related information.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

regarding which iova range jpgenc actually locate, it
depends on the dma-ranges property of vdec dtsi node.

The bus_info field is set by most drivers based on the type of the device
bus as well as the name of the device. Do this in v4l_querycap() so
drivers don't need to. This keeps compatibility with non-default and silly
bus_info.
