From cbe6ab84f6dbf68a5c79cb70e09f5c3a8f77b9e1 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 24 Jan 2014 08:01:21 +0000 Subject: [PATCH] libxc/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.
