[PATCH 5.4 358/434] ibmvnic: Fix completion structure initialization
From: Greg Kroah-Hartman
Date: Sun Dec 29 2019 - 13:02:37 EST
From: Thomas Falcon <tlfalcon@xxxxxxxxxxxxx>
[ 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.
