[libcamera-devel] [PATCH 2/4] ipa: raspberrypi: cam_helper: Make exposure conversion functions virtual

[Laurent Pinchart]

From: Naushir Patuck <naush at raspberrypi.com>

Some sensors (namely the Sony IMX296, whose support will be added
shortly) require different conversion formulas between exposure time and
exposure lines. Make the Exposure() and ExposureLines() functions
virtual to allow this.
