+Subject: cxl: Don't remove AFUs/vPHBs in cxl_reset
+
+From: Daniel Axtens <dja@axtens.net>
+
+commit 4e1efb403c1c016ae831bd9988a7d2e5e0af41a0 upstream.
+
+If the driver doesn't participate in EEH, the AFUs will be removed
+by cxl_remove, which will be invoked by EEH.
+
+If the driver does particpate in EEH, the vPHB needs to stick around
+so that the it can particpate.
+
+In both cases, we shouldn't remove the AFU/vPHB.
