OK, thanks. The first of the following two patches is a slightly modified version of the one that you commented. Patch [2/2] implements the idea for platform devices and since it modifies struct platform_device_info, I'm adding a CC to Greg. The patches are on top of current linux-pm.git/linux-next. It looks like we may be able to use this approach for PCI too, in which case the whole .find_device() stuff won't be necessary any more. Thanks, Rafael -- I speak only for myself. Rafael J.
