Move all the life cycle of the name to add_mapping. This simplifies the error handling inside uvc_ioctl_ctrl_map and solves a memory leak when kemmdup fails. Also make sure that for custom controls, the user provides a valid name.

The list iterator will point to a bogus position containing HEAD if the list is empty or the element is not found in list. This case should be checked before any use of the iterator, otherwise it will lead to a invalid memory access. The missing check here is before "pin = iterm->id;", just add check here to fix the security bug. In addition, the list iterator value will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the element is not found in list, considering the (mis)use here: "if (iterm == NULL". Use a new value 'it' as the list iterator, while use the old value 'iterm' as a dedicated pointer to point to the found element, which 1. can fix this bug, due to 'iterm' is NULL only if it's not found. 2. do not need to change all the uses of 'iterm' after the loop. 3. can also limit the scope of the list iterator 'it' *only inside* the traversal loop by simply declaring 'it' inside the loop in the future, as usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Fixes: d5e90b7a ("[media] uvcvideo: Move to video_ioctl2") Signed-off-by:

The mipi_csis_dump_regs() function accesses the interface registers in order to printout their values for debug purposes. As the function access the registers, it requires the interface to be powered up. Currently this is only enforced in one of the function's callers (mipi_csis_log_status)() but not when the function is called by the debugfs attribute handler. Make sure to access registers only if the interface is powered up and remove the same check from the caller. Signed-off-by:

The mipi_csis_device.powered flag only serves for the purpose of not accessing registers in mipi_csis_log_status() when the interface is not powered up. Instead of manually tracking the power state, rely on pm_runtime_get_if_in_use() to remove the 'powered' flag. Also remove the locking in the function as runtime_pm() is refcounted and there's no risk of the interface being powered down behind our backs. Signed-off-by:

The runtime PM resume handler is guaranteed to be called on a suspended device, and the suspend handler on a resumed device. The implementation can thus be simplified. While at it, rename the mipi_csis_device state field to powered, as the now state contains a single flag only. Signed-off-by:

The subdev .s_power() operation is deprecated. Drop it, requiring sensor drivers to correctly use runtime PM instead of relying on .s_power(). As this driver has just been moved out of staging, and necessary drivers to implement a full camera pipeline are still in staging, no platform depends yet on this API being called. There is thus no risk of regression. Signed-off-by:

The payload size for encoder capture buffers is set by the driver upon finishing encoding each frame, based on the encoded length returned from hardware, and whatever header and padding length used. Setting a non-zero default serves no real purpose, and also causes issues if the capture buffer is returned to userspace unused, confusing the application. Instead, always set the payload size to 0 for encoder capture buffers when preparing them.

The V4L2 stateful encoder uAPI specification requires that drivers support the ENCODER_CMD ioctl to allow draining of buffers. This however was not implemented, and causes issues for some userspace applications. Implement support for the ENCODER_CMD ioctl using v4l2-mem2mem helpers. This is entirely based on existing code found in the vicodec test driver. Fixes: 775fec69 ("media: add Rockchip VPU JPEG encoder driver") Signed-off-by:

The CODA960 manual states that ASO/FMO features of baseline are not supported, so for this reason this driver should only report constrained baseline support. This fixes negotiation issue with constrained baseline content on GStreamer 1.17.1. ASO/FMO features are unsupported for the encoder and untested for the decoder because there is currently no userspace support. Neither GStreamer parsers nor FFMPEG parsers support ASO/FMO.
