commit 7e98c295c1bb511e [kernel-yocto: ensure that only a single defconfig is processed] has an overly broad replacement strategy for 'defconfig' and hence will chop up any fragment name that happens to contain that string. If we change the processing to split on whitespace and drop any full work 'defconfig' fragments, we'll get the behaviour we want (no duplicate defconfigs, but fragments with defconfig in their name are fine). [YOCTO #12487] (From OE-Core rev: 7c5a6cd8afb7157890b30a3e19ed5c06ec5a9516) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
