media: bcm2835-unicam: Disable trigger mode operation

2025-02-21T13:10:53+00:00

[ Upstream commit 697a252bb2ea414cc1c0b4cf4e3d94a879eaf162 ] The imx219/imx708 sensors frequently generate a single corrupt frame (image or embedded data) when the sensor first starts. This can either be a missing line, or invalid samples within the line. This only occurrs using the upstream Unicam kernel driver. Disabling trigger mode elimiates this corruption. Since trigger mode is a legacy feature copied from the firmware driver and not expected to be needed, remove it. Tested on the Raspberry Pi cameras and shows no ill effects.

media: venus: destroy hfi session after m2m_ctx release

2025-02-17T10:36:47+00:00

commit df4ff47448fe0d392b29868e8398e3b0e587514d upstream. This partially reverts commit that made hfi_session_destroy() the first step of vdec/venc close(). The reason being is a regression report when, supposedly, encode/decoder is closed with still active streaming (no ->stop_streaming() call before close()) and pending pkts, so isr_thread cannot find instance and fails to process those pending pkts. This was the idea behind the original patch - make it impossible to use instance under destruction, because this is racy, but apparently there are uses cases that depend on that unsafe pattern. Return to the old (unsafe) behaviour for the time being (until a better fix is found).

media: nuvoton: Fix an error check in npcm_video_ece_init()

2025-02-17T10:36:47+00:00

commit c4b7779abc6633677e6edb79e2809f4f61fde157 upstream. When function of_find_device_by_node() fails, it returns NULL instead of an error code. So the corresponding error check logic should be modified to check whether the return value is NULL and set the error code to be returned as -ENODEV.

media: mmp: Bring back registration of the device

2025-02-17T10:36:46+00:00

commit fbb5298bf1a7b71723cd2bb193642429ceb0fb84 upstream. In commit 4af65141e38e ("media: marvell: cafe: Register V4L2 device earlier"), a call to v4l2_device_register() was moved away from mccic_register() into its caller, marvell/cafe's cafe_pci_probe(). This is not the only caller though -- there's also marvell/mmp. Add v4l2_device_register() into mmpcam_probe() to unbreak the MMP camera driver, in a fashion analogous to what's been done to the Cafe driver. Same for the teardown path.

media: imx-jpeg: Fix potential error pointer dereference in detach_pm()

2025-02-08T09:02:25+00:00

commit 1378ffec30367233152b7dbf4fa6a25ee98585d1 upstream. The proble is on the first line: if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i])) If jpeg->pd_dev[i] is an error pointer, then passing it to pm_runtime_suspended() will lead to an Oops. The other conditions check for both error pointers and NULL, but it would be more clear to use the IS_ERR_OR_NULL() check for that.
