If anyone has any objections, please let me know. ------------------ From: Jiale Yao [ Upstream commit 2f3196d27e3bfcee0569d23a123aedcc6ddd39f1 ] A device bound through driver_override need not match an entry in the driver tables. In that case spi_get_device_match_data() returns NULL, but the result is later dereferenced by the property parsing and initialization paths. Reject devices without match data before continuing probe.
