Yes, it makes it easier to select misc device drivers from Kconfig files. But it also makes it impossible to deselect all misc device drivers at once. I think that what we really need is the implementation in the Kconfig system of smart selects, i.e. whenever an entry is selected, everything it depends on gets selected as well. I don't know how feasible this is, but if it can be done then I'd prefer this to your proposal. Meanwhile, I am not in favor of applying your patch. The benefit is relatively small IMHO (misc device drivers are rarely selected) and there is one significant drawback. That being said, I'm not the one to decide, so if you can convince someone with more power (aka Andrew Morton)... > > config AD525X_DPOT > tristate "Analog Devices Digital Potentiometers" > @@ -344,6 +328,12 @@ config ISL29020 > This driver can also be built as a module.
