If anyone has any objections, please let me know. ------------------ From: Jiale Yao [ Upstream commit 2c01a0a1c5550b4f502c7747c06d2e57a240cd87 ] 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 adis16400_probe() immediately dereferences the result. Validate the match data before it is used.
