I didn't quite understand that variable.
But I saw the same paramter in 'drivers/misc/mei/bus.c +1001' where has comments.
So I copied that comments here.
997 /** 998 * mei_cl_device_uevent - me client bus uevent handler 999 * 1000 * @dev: device 1001 * @env: uevent kobject 1002 * 1003 * Return: 0 on success -ENOMEM on when add_uevent_var fails 1004 */ 1005 static int mei_cl_device_uevent(struct device *dev, struct kobj_uevent_env *env)
Thank you for your advice.
I'm about to send a patch v2 with the changes suggested by you.
Best Regards.
