backport kernel commit 59faba1b316a7798a33752b3889193333f8af1a0
From: Mauro Carvalho Chehab <mchehab@infradead.org> Original patch from Trent Piepho <xyzzy@speakeasy.org>. Its description: Fix Kconfig dependency problems wrt boolean menuconfigs If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool promotes the tristate from m to y. This ends up causing a problem with several menuconfigs that look like: menuconfig BAR bool depends on BAZ [tristate] if BAR config FOO tristate endif The solution used here is to add the dependencies of BAR to the if statement, so that items in the if block will gain a direct non-bool-promoted dependency on BAZ. This is how it would work if a menu was used instead of an if block. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
