If no other external reference to device before put_device in device_unregister, dev.release will be called from put_device to free something, which depends on your implement for dev.release. > ex. > file : drivers/usb/gadget/fsl_udc_core.c > function : static int __init fsl_udc_probe(struct platform_device *pdev) Once reaches err_unregister, double free of udc_controller may be triggered, so fix should be needed. -- Lei Ming -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
