[libcamera-devel] [PATCH 18/18] ipa: ipu3: Implement an empty stop() function

[Jean-Michel Hautbois]

While the stop() method does not currently perform any action, it forms
part of the IPA interface and is a public function in the class.

Promote it to a full (but basic) function implementation and begin the
documentation accordingly so that there is an appropriate stub to
perform stop operations if they come up.
