Move incrementing/decrementing runtime PM count to imx219_start_streaming()/imx219_stop_streaming() functions respectively. This fixes an issue of unbalanced runtime PM count in resume callback error path where streaming is stopped and runtime PM count is left unbalanced.

Move out locking/unlocking of vflip and hflip controls from imx219_set_stream() to the imx219_start_streaming()/ imx219_stop_streaming() respectively. This fixes an issue in resume callback error path where streaming is stopped and the controls are left in locked state. Fixes: 1283b3b8 ("media: i2c: Add driver for Sony IMX219 sensor") Reported-by:

Rename v4l2_async_register_subdev_sensor_common as v4l2_async_register_subdev_sensor. This is a part of the effort to make the long names present in V4L2 fwnode and async frameworks shorter. Signed-off-by:

Rename v4l2_async_notifier_parse_fwnode_sensor_common() as v4l2_async_notifier_parse_fwnode_sensor() and make the function static, as it's not used by a driver and maybe never will. Signed-off-by:

It was always assumed that walking the media graph would require holding the media_device graph_mutex but this was not documented nor checked for. Add a lockdep check to graph walk init and iter, and document the need for acquiring the graph_mutex. Signed-off-by:

If there in an error during a set_fmt, do not overwrite the previous sizes with the invalid config.

When __v4l2_ctrl_modify_range() fails, no error return code of imx274_s_frame_interval() is assigned. To fix this bug, ret is assigned with the return valye of __v4l2_ctrl_modify_range(), and then ret is checked. Reported-by:

The driver uses v4l2_get_link_freq() helper to obtain the link frequency using the LINK_FREQ but also the PIXEL_RATE control. The divisor for the pixel rate derived link frequency was wrong, missing the bus uses double data rate. Fix this. Reported-by:

Fix sub-device function for the pixel array and the scaler. It seems that the pixel array had gotten assigned as SCALER whereas the scaler had CAM_SENSOR function.

Some devices reference an output terminal as the source of extension units. This is incorrect, as output terminals only have an input pin, and thus can't be connected to any entity in the forward direction. The resulting topology would cause issues when registering the media controller graph. To avoid this problem, connect the extension unit to the source of the output terminal instead. While at it, and while no device has been reported to be affected by this issue, also handle forward scans where two output terminals would be connected together, and skip the terminals found through such an invalid connection.

The .link_setup() handler uses state->lock to protect the src_sd field. This is only used in mipi_csis_s_stream(), which can't race .link_setup() as the MC core prevents link setup when the pipeline is streaming. Drop the lock. Signed-off-by:

The reset-names property is incorrect, as it references the reset of the MIPI D-PHY master, which is used by the DSI controller. Fixing the property name would create backward-compatibility issues. As the device has a single reset, we can instead drop reset-names completely, which also simplifies the binding. Fix the example accordingly to use the correct reset. Signed-off-by:

If some error occurs, URB buffers should also be freed. If they aren't freed with the dvb here, the em28xx_dvb_fini call doesn't frees the URB buffers as dvb is set to NULL. The function in which error occurs should do all the cleanup for the allocations it had done. Tested the patch with the reproducer provided by syzbot. This patch fixes the memleak.
