Hi, When going through our patches to be mainlined I stumbled on this one which we have fixed in many different ways internally. The problem is a NULL pointer dereference that can be triggered by disconnecting the USB cable at a specific time. Before submitting the final patch I would like to hear which solution you'd prefer. As I see it there are four different ways to fix the problem: 1) Remove the ERROR() call completely. 2) Add an if-statement on cdev in rndis_response_complete() and use pr_err() or ERROR(). 3) Globally update the ERROR() macro to handle the case where cdev is null. 4) Use the attached patch (RFC PATCH 1/1) where ERROR() is simply replaced with pr_err(). Thanks! -Oskar Truls Bengtsson (1): usb: f_rndis: Avoid to use ERROR macro if cdev can be null drivers/usb/gadget/f_rndis.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) -- 1.7.8.6 -- 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
