Subject: [PATCH] platform/x86: ISST: Fix wrong unregister type
Git-commit: 6cc8f6598978b8f30e70bc12f28fbbc9e26227cc
Patch-mainline: v5.7-rc1
References: bsc#1171810

The MMIO driver is not unregistering with the correct type with the ISST
common core during module removal. This should be unregistered with
ISST_IF_DEV_MMIO instead of ISST_IF_DEV_MBOX.
