[PATCH v3 1/3] PCI: endpoint: Fix that API devm_pci_epc_destroy() fails to destroy the EPC device

[Zijun Hu]

From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>

For devm_pci_epc_destroy(), its comment says it needs to destroy the EPC
device, but it will not actually do that since devres_destroy() does not
call devm_pci_epc_release(), and it also can not fully undo what the API
devm_pci_epc_create() does, so it is faulty.

Fortunately, the faulty API has not been used by current kernel tree.
Fixed by using devres_release() instead of devres_destroy() within the API.

Fixes: 5e8cb4033807 ("PCI: endpoint: Add EP core layer to enable EP controller and EP functions")
