Subject: Decompressors: check for write errors in decompress_unlzo.c
From: Lasse Collin <lasse.collin@xxxxxxxxxxx>
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.
