Subject: [PATCH] xprtrdma: Fix a maybe-uninitialized compiler warning
Date:   Sun, 31 Oct 2021 09:08:49 -0400
Message-Id: <2b32d41cf6a502918a685447cd749c4b1cb0d16d.1635685588.git.bcodding@redhat.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

This minor fix-up keeps GCC from complaining that "last' may be used
uninitialized", which breaks some build workflows that have been running
with all warnings treated as errors.
