If anyone has any objections, please let me know. ------------------ From: Pengpeng Hou [ Upstream commit 415c63896b76fd98883e190bc7518383cb01779c ] The driver stores chip metadata in both the OF match table and the I2C id table, but probe currently reads it with device_get_match_data(). That helper only returns firmware-node match data, so an I2C-id/modalias match can leave chip_data NULL before the driver dereferences it to read ngpio. Use i2c_get_match_data() so the I2C id table driver_data is consumed when firmware match data is not present.
