Yes, I suspected the issue appeared after recent change commit 88e85861b4f77ae29495ee05574c98dd0c6c3037 [media] v4l2-ctrl: Add helper function for the controls range update Then it is related to to 3.9-rc1+ kernels only. I have verified it on 3.8 based kernel and there is no issue with drivers that do not initialize step value for boolean type controls properly. It only appears after the above commit is applied. I've picked your fixup patches into v3.9-fixes branch and will try to send them out this week, together with other patches from our side.
