#     kconfig: make 'imply' obey the direct dependency
#     
#     The 'imply' statement may create unmet direct dependency when the
#     implied symbol depends on m.
#     
#     [Test Code]
#     
#       config FOO
#               tristate "foo"
#               imply BAZ
#     
#       config BAZ
#               tristate "baz"
#               depends on BAR
#     
#       config BAR
#               def_tristate m
#     
#       config MODULES
#               def_bool y
#               option modules
#     
#     If you set FOO=y, BAZ is also promoted to y, which results in the
#     following .config file:
#     
#       CONFIG_FOO=y
#       CONFIG_BAZ=y
#       CONFIG_BAR=m
#       CONFIG_MODULES=y
#     
#     This does not meet the dependency 'BAZ depends on BAR'.
#     
#     Unlike 'select', what is worse, Kconfig never shows the
#     'WARNING: unmet direct dependencies detected for ...' for this case.
#     
#     Because 'imply' is considered to be weaker than 'depends on', Kconfig
#     should take the direct dependency into account.
#     
#     For clarification, describe this case in kconfig-language.rst too.
