From ec6452a5ec68498221a0ced3443cefd65b08be36 Mon Sep 17 00:00:00 2001 From: Arnaud Lacombe Date: Wed, 8 Jun 2011 01:42:11 -0400 Subject: [PATCH] kconfig: do not overwrite symbol direct dependency in assignment Considering the following configuration: config F bool "F" choice AB bool "AB" config A bool "A" config B bool "B" endchoice if A config D bool default y if F select E config E bool "E" endif if B config D bool default y if F select E config E bool "E" endif The following configuration: CONFIG_F=y CONFIG_A=y # CONFIG_B is not set CONFIG_D=y CONFIG_E=y emits a spurious warning: (D) selects E which has unmet direct dependencies (B) If a symbol appears in two different branch of the tree, it should inherit the dependency of both parent, not just the last one.
