Subject: [PATCH 1/1] IB/hfi1: Insure freeze_work work_struct is canceled on
Git-commit: 6d517353c70bb0818b691ca003afdcb5ee5ea44e
Patch-mainline: v5.10-rc1
References: bsc#1111666
shutdown
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.
