[libcamera-devel] [PATCH v3 02/11] libcamera: ipu3: imgu: Configure the stat video device as part of configure()

[Niklas Söderlund]

There is no reason to expose and call a separate configureStat() when
the statistics video device can be configured with the exact same
parameters as part of configure(). Move the configuration internally to
the ImgUDevice simplifying the interface, there is no functional change.
