CONFIG_OF not enabled.
Does it make sense to remove of_match_ptr() ?
static struct platform_driver i3c_hci_driver = {
.probe = i3c_hci_probe,
.remove = i3c_hci_remove,
.driver = {
.name = "mipi-i3c-hci",
.of_match_table = of_match_ptr(i3c_hci_of_match),
},
That... or having #ifdef CONFIG_OF around struct of_device_id.
