If anyone has any objections, please let me know. ------------------ From: Jiale Yao [ Upstream commit 9f6d174e9fa5b265e7a0a6caa0c5b579bf899702 ] SPI driver_override allows a device to bind to this driver without matching either the OF or SPI device ID table. In that case, spi_get_device_match_data() returns NULL. adxl380_spi_probe() passes the result to adxl380_probe(), which dereferences chip_info to set the IIO device name and operations, causing a NULL pointer dereference. Commit 572a00852635 ("iio: dac: ad5686: missing NULL check on match data") fixed the same driver_override issue in another SPI driver. Reject devices without match data in the SPI frontend.
