There is no need for explicit calls of devm_kfree(), as the allocated memory will be freed during driver's detach. The driver core clears the driver data to NULL after device_release. Thus, it is not needed to manually clear the device driver data to NULL. So remove the unnecessary pci_set_drvdata() and devm_kfree().
