A more common approach than lock ordering, particularly for application programming (as opposed to operating system or device driver programming), is to use coarser locking — use a …

In computer science, a lock or mutex (from mutual exclusion) is a synchronization primitive that prevents state from being modified or accessed by multiple threads of execution at once.

The common solution to preventing deadlock in code is to make sure the sequence of locking occur in a common manner regardless of which thread is accessing the resources.
