Subject: bzip2/lzma: don't leave empty files around on failure
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ab59d3b70f7a47987f80e153d828363faec643fe;p=openwrt%2Fstaging%2Fblogic.git

bzip2/lzma: don't leave empty files around on failure

Impact: Bugfix, silent build failures

Fix a bug in gen_initramfs_list.sh: in case of failure, it left an
empty output file behind, messing up the next make.
