The line numers for if-entries in the menu tree are off by one or more lines which is confusing when debugging for correctness of unrelated changes. According to the git log, commit a02f0570ae201c49 (kconfig: improve error handling in the parser) was the last one that changed that part of the parser and replaced "if_entry: T_IF expr T_EOL" by "if_entry: T_IF expr nl" but the commit message does not state why this has been done. When reverting that part of the commit, only the line numers are corrected (checked with cdebug = DEBUG_PARSE in zconf.y), otherwise the menu tree remains unchanged (checked with zconfdump() enabled in conf.c). An example for the corrected line numbers: drivers/soc/Kconfig:15:source drivers/soc/tegra/Kconfig drivers/soc/tegra/Kconfig:4:if drivers/soc/tegra/Kconfig:6:if changes to: drivers/soc/Kconfig:15:source drivers/soc/tegra/Kconfig drivers/soc/tegra/Kconfig:1:if drivers/soc/tegra/Kconfig:4:if Signed-off-by: Dirk Gouders <dirk@gouders.net> --- scripts/kconfig/zconf.y | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
