+Subject: [PATCH] x86/amd_nb: Add PCI ID for family 19h model 78h
+References: bsc#1012628
+Patch-mainline: 6.3.3
+Git-commit: 23a5b8bb022c1e071ca91b1a9c10f0ad6a0966e9
+
+commit 23a5b8bb022c1e071ca91b1a9c10f0ad6a0966e9 upstream.
+
+Commit
+
+  310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")
+
+switched to using amd_smn_read() which relies upon the misc PCI ID used
+by DF function 3 being included in a table.  The ID for model 78h is
+missing in that table, so amd_smn_read() doesn't work.
+
+Add the missing ID into amd_nb, restoring s2idle on this system.
+
+  [ bp: Simplify commit message. ]
+
+Fixes: 310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")
