Subject: bzip2/lzma: don't stop search at first unconfigured compression
X-Git-Tag: firefly_0821_release~15200^2~7
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e4aa7ca5a2e6d44f07ceb87d9448113f5b48a334;p=firefly-linux-kernel-4.4.55.git

bzip2/lzma: don't stop search at first unconfigured compression

Impact: Bugfix, avoids kernels which build but panic on boot

Fix a bug in decompress.c : only scanned until the first
non-configured compressor (with disastrous result especially if that
was gzip.)
