5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Radek Krejci <radek.krejci@xxxxxxxxxx>
[ Upstream commit 5d9a16b2a4d9e8fa028892ded43f6501bc2969e5 ]
get_line() does not trim the leading spaces, but the
parse_source_files() expects to get lines with source files paths where
the first space occurs after the file path.
Fixes: 70f30cfe5b89 ("modpost: use read_text_file() and get_line() for reading text files")
