commit 21c5ba161a8b02afd0f6c32c26c10c2a66c63f04 Author: Old-Ding <[email protected]> AuthorDate: Mon Jul 6 04:48:26 2026 +0800 tools: kconfig2html: Handle blank input lines read_line() removes a trailing newline and then checks g_line[len - 1] for a line-continuation backslash. A blank line leaves len at zero, so the continuation check reads before g_line. Return the empty line to the caller before checking for a continuation. kconfig_line() already skips empty lines, so parser behavior is unchanged.
