+Subject: mei: hbm: drop capability response on early shutdown
+
+From: Alexander Usyskin <alexander.usyskin@intel.com>
+
+commit 68553650bc9c57c7e530c84e5b2945e9dfe1a560 upstream.
+
+Drop HBM responses also in the early shutdown phase where
+the usual traffic is allowed.
+Extend the rule that drop HBM responses received during the shutdown
+phase by also in MEI_DEV_POWERING_DOWN state.
+This resolves the stall if the driver is stopping in the middle
+of the link initialization or link reset.
+
+Drop the capabilities response on early shutdown.
+
+Fixes: 6d7163f2c49f ("mei: hbm: drop hbm responses on early shutdown")
