Subject: bzip2/lzma: don't stop search at first unconfigured compression
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e4aa7ca5a2e6d44f07ceb87d9448113f5b48a334;p=linux-beck.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.)
