[RFC][PATCH] Make entries in the "Device drivers" menu individuallyselectable
From: Robert P. J. Day
Date: Thu Dec 14 2006 - 03:36:02 EST
i've posted on this before so here's a slightly-updated patch that
uses the kbuild "menuconfig" feature to make numerous entries under
the Device drivers menu selectable on the spot. if folks think this
is a good idea, what's the best way to get it in?
i could officially submit the patch as is or, if that's too
wide-sweeping since it hits a lot of subsystems, leave it up to the
individual subsystem maintainers to decide for themselves and submit
their own patch.
(the patch below modifies those entries for which a "menuconfig"
entry was immediately obvious and shouldn't affect any of the
underlying logic. that's why some entries were deliberately left out
of the patch, at least for now.)
