Subject: tristate choices with mixed tristate and boolean values
From: "Jan Beulich" <[EMAIL PROTECTED]>
Change kconfig behavior so that mixing bool and tristate config settings in
a choice is possible and has the desired effect of offering just the
tristate options individually if the choice gets set to M, and a normal
boolean selection if the choice gets set to Y.
