From 9f0e96713033e5fe5a7a232e2c3aa994a8d2862f Mon Sep 17 00:00:00 2001 From: Jiale Yao Date: Fri, 25 Sep 2026 20:57:46 +0800 Subject: [PATCH] iio: adc: ti-ads131m02: reject devices without match data 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. ads131m_probe() immediately dereferences the returned configuration to initialize the IIO device, 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 before using the configuration.
