Subject: modpost: remove get_next_text() and make {grab,release_}file static
Was-Git-commit: 75893572d45399cefbb88443d0878adae9cb0b41
Was-Patch-mainline: v5.8-rc1
Patch-mainline: Never, this revert is SUSE-specific
References: required by patches.suse/add-suse-supported-flag.patch

get_next_line() is no longer used. Remove.

grab_file() and release_file() are only used in modpost.c. Make them
static.
