From f55ffe6bd8b844a8cd9956702f42ac2eb96ad56f Mon Sep 17 00:00:00 2001
From: Darren Kenny <darren.kenny@oracle.com>

Subject: [PATCH] zstd: Initialize seq_t structure fully
While many compilers will initialize this to zero, not all will, so it
is better to be sure that fields not being explicitly set are at known
values, and there is code that checks this fields value elsewhere in the
code.
Fixes: CID 292440
