6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx> [ Upstream commit d4929755e4d02bd3de3ae5569dab69cb9502c54f ] The devm_pci_epc_destroy() comment says destroys the EPC device, but it does 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. Use devres_release() instead of devres_destroy() so the EPC device will be released.
