If anyone has any objections, please let me know. ------------------ From: Andy Shevchenko [ Upstream commit ebee9004cc0200b2b708ebf7ac625d35c71c049f ] Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override() so platform drivers that rely on the existence of a device's driver data need to verify its presence. Accordingly, add requisite match and driver data checks against NULL to the driver where they are missing.
