Laurent, Sakari,
While I was trying to adapt my Zoom2/3 sensor drivers into latest 'devel' branch with latest commit:
commit 2e7d09ec5e09ee80462a611c9958e99866ee337c
Author: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>

Work in progress
Signed-off-by: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>
And applying the attached patches. I see the following kernel panic on bootup:
