[libcamera-devel] [PATCH v4 1/4] ipa: raspberrypi: Make CamHelper exposure methods virtual

[David Plowman]

This allows derived classes to override them if they have any special
behaviours to implement. For instance if a particular camera mode
produces a different signal level to other modes, you might choose to
address that in the gain or exposure methods.
