The imgu_rpm_dummy_cb() looks like an API misuse that is explained in the comment above it. Aside from that, it also causes a warning when power management support is disabled: drivers/staging/media/ipu3/ipu3.c:794:12: error: 'imgu_rpm_dummy_cb' defined but not used [-Werror=unused-function] The warning is at least easy to fix by marking the function as __maybe_unused.

The v4l2_pix_format_mplane structure is too large to be put on the kernel stack, as we can see in 32-bit builds: drivers/staging/media/ipu3/ipu3-v4l2.c: In function 'imgu_fmt': drivers/staging/media/ipu3/ipu3-v4l2.c:753:1: error: the frame size of 1028 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] By dynamically allocating this array, the stack usage goes down to an acceptable 272 bytes for the same x86-32 configuration.

When start_streaming was called both last_src_buf and last_dst_buf pointers were set to NULL, but this depends on whether the capture or output queue starts streaming. When decoding with resolution changes in between the capture queue has to restart streaming whenever a resolution change occurs. And that would reset last_src_buf as well, which causes a problem if the decoder was stopped by the application. Since last_src_buf is now NULL, the LAST flag is never set for the last capture buffer. Signed-off-by:

Some functions like enum_fmt use the buffer type as was passed from userspace, which might cause the switch to fall into the default case. Just drop the WARN_ON(1) to avoid kernel log pollution. Signed-off-by:

si2165_readreg8() may fail. Looking into si2165_readreg8(), we will find that "val_tmp" will be an uninitialized value when regmap_read() fails. "val_tmp" is then assigned to "val". So if si2165_readreg8() fails, "val" will be a random value. Further use will lead to undefined behaviors. The fix checks if si2165_readreg8() fails, and if so, returns its error code upstream.

Ref: https://bugzilla.kernel.org/show_bug.cgi?id=199323 Users are experiencing problems with the DVBSky S960/S960C USB devices since the following commit: 9d659ae1: ("locking/mutex: Add lock handoff to avoid starvation") The device malfunctions after running for an indeterminable period of time, and the problem can only be cleared by rebooting the machine. It is possible to encourage the problem to surface by blocking the signal to the LNB. Further debugging revealed the cause of the problem.

Commit 14f4eaed ("media: dvbsky: fix driver unregister logic") fixed a use-after-free by removing the reference to the frontend after deleting the backing i2c device. This has the unfortunate side effect the frontend device is never freed in the dvb core leaving a dangling device, leading to errors when the dvb core tries to register the frontend after e.g. a replug as reported here: https://www.spinics.net/lists/linux-media/msg138181.html media: dvbsky: issues with DVBSky T680CI === [ 561.119145] sp2 8-0040: CIMaX SP2 successfully attached [ 561.119161] usb 2-3: DVB: registering adapter 0 frontend 0 (Silicon Labs Si2168)... [ 561.119174] sysfs: cannot create duplicate filename '/class/dvb/ dvb0.frontend0' === The use after free happened as dvb_usbv2_disconnect calls in this order: - dvb_usb_device::props->exit(...) - dvb_usbv2_adapter_frontend_exit(...) + if (fe) dvb_unregister_frontend(fe) + dvb_usb_device::props->frontend_detach(...) Moving the release of the i2c device from exit() to frontend_detach() avoids the dangling pointer access and allows the core to unregister the frontend. This was originally reported for a DVBSky T680CI, but it also affects the MyGica T230C. As all supported devices structure the registration/ unregistration identically, apply the change for all device types. Signed-off-by:

When streaming is stopped all URBs are killed, but in fill_frame and in bulk_irq this results in an attempt to resubmit the killed URB. That is not what you want and causes spurious kernel messages. So check if streaming has stopped before resubmitting. Also check against gspca_dev->streaming rather than vb2_start_streaming_called() since vb2_start_streaming_called() will return true when in stop_streaming, but gspca_dev->streaming is set to false when stop_streaming is called.

Two saa7146/hexium files contain a construct that causes a warning when built with clang: drivers/media/pci/saa7146/hexium_orion.c:210:12: error: stack frame size of 2272 bytes in function 'hexium_probe' [-Werror,-Wframe-larger-than=] static int hexium_probe(struct saa7146_dev *dev) ^ drivers/media/pci/saa7146/hexium_gemini.c:257:12: error: stack frame size of 2304 bytes in function 'hexium_attach' [-Werror,-Wframe-larger-than=] static int hexium_attach(struct saa7146_dev *dev, struct saa7146_pci_extension_data *info) ^ This one happens regardless of KASAN, and the problem is that a constructor to initialize a dynamically allocated structure leads to a copy of that structure on the stack, whereas gcc initializes it in place.

The ISC driver currently supports ITU-R 601 encoding which utilizes the external hsync and vsync signals. ITU-R 656 format removes the need for these pins by embedding the sync pulses within the data packet. To support this feature, enable necessary register bits when this feature is enabled via device tree. Signed-off-by:
