From 55d207597e05b79fb0d90868abfe0f77b3ba66f2 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 28 Jan 2014 13:31:28 +0100 Subject: [PATCH] xen/unlz4: always set an error return code on failures "ret", being set to -1 early on, gets cleared by the first invocation of lz4_decompress()/lz4_decompress_unknownoutputsize(), and hence subsequent failures wouldn't be noticed by the caller without setting it back to -1 right after those calls.
