Thanks to all for clarifications. Since everyone is convinced, that that idle function in mmc bus.c is appropriate, I restored it and managed to achieve my goals also without it by adjusting the platform runtime pm and power domain prototype support. But I still need those "cheating" calls to pm_runtime_put_noidle(&pdev->dev); and pm_runtime_get_noresume(&pdev->dev); in the sh_mmcif.c driver. If I use the patch as posted at http://article.gmane.org/gmane.linux.ports.sh.devel/10724 but without those two calls, and load and unload the driver, while a card is plugged in, unloading the driver doesn't power down the interface, because the usage_count == 1 also after the kernel has soft-ejected the card mmc0: card 0001 removed With my put_noidle() / get_noresume() hack all cases of modprobe / rmmod, card insert / eject work correctly.
