When adding support for parallel subdev for Gen3 it was missed that the symbol 'i' in rvin_group_link_notify() was already declared, remove the dupe as it's only used as a loop variable this have no functional change.

The V4L2 sub-device API does not support the crop default target. A number of drivers apparently still did support this, likely as it was needed by the SoC camera framework. Drop support for the default crop rectaingle in sub-device drivers, and use the bounds rectangle in SoC camera instead. Reported-by:

Sakari Ailus authored
A number of sub-device drivers used a static name for the sub-device, and thus the media entity. As the entity name must be unique within a media device, this makes it impossible to have more than one instance of each device in a media device. This is a rather severe limitation. Instead of fixing these drivers, add a comment to the drivers noting that such static names may not be used in the future. The alternative of fixing the drivers is troublesome as the entity (as well as sub-device) name is part of the uAPI. Changing that is almost certain to break something. As these devices are old but no-one has encountered a problem with the static names, leave it as-is. Signed-off-by:

If au0828_analog_register fails, the dev is kfree'd and then flow jumps to done, which can call au0828_usb_disconnect. Since all USB error codes are negative, au0828_usb_disconnect will be called. The problem is au0828_usb_disconnect uses dev, if dev is NULL then there is immediate oops encountered.

On a decoder instance, after the profile has been parsed from the stream __v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the read-only profile control. This ends up calling back into the CODA driver where a missing check on the s_ctrl caused the profile information that has just been parsed from the stream to be overwritten with the default baseline profile. Later on the driver fails to enable frame reordering, based on the wrong profile information.
