2021-10-05media: aspeed: refine to avoid full jpeg updateJammy Huang1-1/+16
The switch of jpeg 420/444 subsampling will update full jpeg header for aspeed now. Just update the 420/444 subsampling part of jpeg header is fine.

If rcsi2_code_to_fmt() return NULL, then null pointer dereference occurs in the next cycle. That should not be possible now but adding checking protects from future bugs. The patch adds checking if format is NULL. Found by Linux Driver Verification project (linuxtesting.org).

2021-09-30media: s5p-jpeg: rename JPEG marker constants to prevent build warningsRandy Dunlap2-23/+23
The use of a macro named 'RST' conflicts with one of the same name in arch/mips/include/asm/mach-rc32434/rb.h. This causes build warnings on some MIPS builds. Change the names of the JPEG marker constants to be in their own namespace to fix these build warnings and to prevent other similar problems in the future.

2021-09-30media: atmel: fix the ispck initializationEugen Hristev4-50/+38
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.

2021-09-30media: rcar-vin: Use user provided buffers when startingNiklas Söderlund1-1/+2
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. The change also fixes a warning produced by v4l2-compliance, warn: v4l2-test-buffers.cpp(448): got sequence number 3, expected 0 [hverkuil: fixed some typos in the Subject and the log message] Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

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().

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.

2021-09-30media: stm32: Potential NULL pointer dereference in dcmi_irq_thread()Dmitriy Ulitin1-8/+11
At the moment of enabling irq handling: 1922 ret = devm_request_threaded_irq(&pdev->dev, irq, dcmi_irq_callback, 1923 dcmi_irq_thread, IRQF_ONESHOT, 1924 dev_name(&pdev->dev), dcmi); there is still uninitialized field sd_format of struct stm32_dcmi *dcmi. If an interrupt occurs in the interval between the installation of the interrupt handler and the initialization of this field, NULL pointer dereference happens. This field is dereferenced in the handler function without any check: 457 if (dcmi->sd_format->fourcc == V4L2_PIX_FMT_JPEG && 458 dcmi->misr & IT_FRAME) { The patch moves interrupt handler installation after initialization of the sd_format field that happens in dcmi_graph_notify_complete() via dcmi_set_default_fmt().
