[PATCH 4.14 33/63] kconfig: fix file name and line number of warn_ignored_character()

From: Greg Kroah-Hartman
Date: Thu Jan 24 2019 - 14:32:15 EST

4.14-stable review patch. If anyone has any objections, please let me know.


[ 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]
