If anyone has any objections, please let me know. ------------------ From: David Heidelberg commit 1dbd46d4b2fb416a8202b1a8e4ef9d0cadbe075f upstream. wled_probe() doesn't set the driver data for the platform device. As a result, platform_get_drvdata() in wled_remove() will return NULL, and the first dereference of it crashes on unbind. Set the platform device driver data in wled_probe().
