What I am against is on a patchset that starts by breaking the USB drivers that use the media controller. Btw, I'm starting to suspect that getting rid of devm_*alloc() on OMAP3, as proposed by the 00/21 thread is addressing a symptom of the problem and not a cause, and that using get_device()/put_device() may help fixing such issues. See Hans comments on that thread.
