Subject: [PATCH AUTOSEL 5.10 30/39] crypto: qat - fix reuse of completion variable
Date: Sun,  5 Sep 2021 21:21:44 -0400	[thread overview]
Message-ID: <20210906012153.929962-30-sashal@kernel.org> (raw)
In-Reply-To: <20210906012153.929962-1-sashal@kernel.org>

From: Marco Chiappero <marco.chiappero@intel.com>

[ Upstream commit 3d655732b0199562267a05c7ff69ecdd11632939 ]

Use reinit_completion() to set to a clean state a completion variable,
used to coordinate the VF to PF request-response flow, before every
new VF request.
