scripts/checkkconfigsymbols.py: support default statements
Until now, checkkonfigsymbols.py did not check default statements for references on missing Kconfig symbols (i.e., undefined Kconfig options). Hence, add support to parse and check the Kconfig default statement. Signed-off-by: Valentin Rothberg <valentinrothberg@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
