[libcamera-devel] [PATCH 0/2] Application support for per-mode sensitivities

[David Plowman]

Hi everyone

This seems to have become a rather forgotten patch set (also here:
https://patchwork.libcamera.org/project/libcamera/list/?series=2183).
In fact it's so old I'd managed to lose the original email that I
sent! So I was wondering if I might give folks a little nudge for some
thoughts on this.

Thanks!
David
