Subject: [PATCH AUTOSEL 5.4 348/350] ibmvnic: Fix completion structure initialization
Date: Tue, 10 Dec 2019 16:07:33 -0500 [thread overview]
Message-ID: <20191210210735.9077-309-sashal@kernel.org> (raw)
In-Reply-To: <20191210210735.9077-1-sashal@kernel.org>
From: Thomas Falcon <tlfalcon@linux•ibm.com>
[ Upstream commit 070eca955c4af1248cb78a216463ff757a5dc511 ]
Fix multiple calls to init_completion for device completion
structures. Instead, initialize them during device probe and
reinitialize them later as needed.
