[ 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 '/'
