Decompressors: check for write errors in decompress_unlzo.c
The return value of flush() is not checked in unlzo(). This means that the decompressor won't stop even if the caller doesn't want more data. This can happen e.g. with a corrupt LZO-compressed initramfs image. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.
