Subject: [PATCH AUTOSEL 4.19 53/97] kconfig: fix file name and line number of warn_ignored_character()
From: Masahiro Yamada <yamada.masahiro@...ionext.com>
[ Upstream commit 77c1c0fa8b1477c5799bdad65026ea5ff676da44 ]
Currently, warn_ignore_character() displays invalid file name and
line number.
The lexer should use current_file->name and yylineno, while the parser
should use zconf_curname() and zconf_lineno().
This difference comes from that the lexer is always going ahead
of the parser. The parser needs to look ahead one token to make a
shift/reduce decision, so the lexer is requested to scan more text
from the input file.
This commit fixes the warning message from warn_ignored_character().
[Test Code]
----(Kconfig begin)----
/
-----(Kconfig end)-----
[Output]
Before the fix:
<none>:0:warning: ignoring unsupported character '/'
After the fix:
Kconfig:1:warning: ignoring unsupported character '/'
