Suppose mutex_lock(A) is called in pre_reset(), one solution is that

We can do it only for devices with storage interface in current
configuration.

The problem will become quite complicated if a 3rd, even 4th,... context
is involved in the task dependency.

But I am wondering if there are such practical examples wrt. usb
mass storage.
