Subject[PATCH 4.19 40/90] IB/hfi1: Insure freeze_work work_struct is canceled on shutdown
Date
[ Upstream commit 6d517353c70bb0818b691ca003afdcb5ee5ea44e ]

By code inspection, the freeze_work is never canceled.

Fix by adding a cancel_work_sync in the shutdown path to insure it is no
longer running.

Fixes: 7724105686e7 ("IB/hfi1: add driver files")
