Hello,
I found a bug in the most usb driver.
When the driver fails at
mdev->conf = kcalloc(num_endpoints, sizeof(*mdev->conf), GFP_KERNEL);
I got the following warning message:
[ 15.406256] kobject: '(null)' (ffff8881068f8000): is not
initialized, yet kobject_put() is being called.

Since I'm not familiar with the driver, I ask for your help to solve
the warning.
regards,
Zheyu Ma
