scripts/config: allow colons in option strings for sed
[ Upstream commit e461bc9f9ab105637b86065d24b0b83f182d477c ] Sed broke on some strings as it used colon as a separator. I made it more robust by using \001, which is legit POSIX AFAIK. E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01" failed with: sed: -e expression #1, char 55: unknown option to `s' Signed-off-by: Jeremie Francois (on alpha) <jeremie.francois@gmail.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
