q->memory entry is initialized to late, so if allocation of memory buffers fails, the buffers might not be freed correctly (q->memory is tested in __vb2_free_mem, which can be called before setting q->memory). Reported-by:

Videobuf2 core assumes that driver doesn't set any buffer flags. This is correct for buffer state flags that videobuf2 manages, but the other flags like V4L2_BUF_FLAG_{KEY,P,B}FRAME, V4L2_BUF_FLAG_TIMECODE and V4L2_BUF_FLAG_INPUT should be passed from or to the driver.

Protecting the color format with vb2_is_streaming() is not sufficient as this prevents changing the format only after VIDIOC_STREAMON. To prevent the color format reconfiguration as soon as buffers are allocated use vb2_is_busy() instead. Also make the videobuf queue ops structure static. Signed-off-by:

Correct pixel limits for the fourth FIMC entity on Exynos4 SoCs. FIMC3 only supports the writeback input from the LCD mixer. Also rename s5pv310 variant to exynos4 which is needed after renaming s5pv310 series to Exynos4. Signed-off-by:

When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISP. However, as other users can be using a different pipeline with other modules, the ISP can't be reset synchronously with the error detection. Mark the ISP as needing a reset when a failure to stop a pipeline is detected, and reset the ISP when the last user releases the last reference to the ISP. Modify the omap3isp_pipeline_set_stream() function to record the new ISP pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

As the number of phases/taps, used to select the correct equations to compute the ratio, depends on the ratio, start with the 7-tap mode equations to compute an approximation of the ratio, and switch to the 4-tap mode equations if the approximation is lower than or equal to 512. Signed-off-by:

If the camera host driver (sh_mobile_ceu_camera.c) is unloaded and then reloaded, probe will fail, because camera client .set_bus_param() and .query_bus_param() methods have been set to NULL. Fix this by caching the original pointers and restoring them on driver-unbind. Signed-off-by:

With the introduction of CSI2 support on sh-mobile, the host driver switched to using v4l2_device_call_until_err() with grp_id == 0 to call subdev operations on the sensor and the CSI2 subdev. However, this has broken multi-client set ups like the one on migor, because that way all operations get called on both clients. To fix this add a grp_id and set it to the client private context.

If allocating stream buffers for one of the primary streams (e.g. YUV) failed during card probe, the error path clean up would try to manipulate the yet unitialized IDX stream structures. This caused a BUG due to unitialized list heads. Detect that case and ignore the uninitialized IDX stream. Signed-off-by:
