A choice member must not depend on another member within the same choice
block.
Kconfig detects this, but the error message is not sensible.
[Test Code]
choice
prompt "choose"
config A
bool "A"
depends on B
config B
bool "B"
endchoice
[Result]
Kconfig:1:error: recursive dependency detected!
Kconfig:1: choice <choice> contains symbol A
Kconfig:4: symbol A is part of choice B
Kconfig:8: symbol B is part of choice <choice>
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
The phrase "part of choice B" is weird because B is not a choice block,
but a choice member.
To determine whether the current symbol is a part of a choice block,
sym_is_choice(next_sym) must be checked.
This commit improves the error message to:
Kconfig:1:error: recursive dependency detected!
Kconfig:1: choice <choice> contains symbol A
Kconfig:4: symbol A symbol is visible depending on B
Kconfig:8: symbol B is part of choice <choice>
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
