From: Vidya Sagar <vidyas@...>

commit 0ef22dcf0c1871888c4c0ee46a9d9c494f2fe997 upstream.

Add support to send notifications to EPF from EPC once the core
registers initialization is complete.

+ * pci_epc_init_notify() - Notify the EPF device that EPC device's core
+ * initialization is completed.
+ * @epc: the EPC device whose core initialization is completeds
+ *
+ * Invoke to Notify the EPF device that the EPC device's initialization
+ * is completed.
+ */
+void pci_epc_init_notify(struct pci_epc *epc)
+ if (!epc || IS_ERR(epc))
+ return;
+ atomic_notifier_call_chain(&epc->notifier, CORE_INIT, NULL);
Is this used somewhere? This adds symbol but noone calls this, and
AFAICT it is not used in the rest of the series, either.

We can merge it, anyway, I guess, but... explanation would be welcome.
