You ask for power cut testing, but when presented with the results, patch is dismissed because I am foolish enough to use a long term stable kernel, and not jump version each time a new kernel comes up. Hopefully, dts will greatly help with migrating kernel, but unoftunately, our camera was developped at the wrong moment (no more board file accepted, yet no dts support for vital peripheral like ISP). It started with one patch, and now tens of them are mentionned, so I understand your concern.
