This patch series improves the arm_ffa notification callback handling by addressing safety and memory issues. It replaces a mutex with an rwlock to prevent sleeping in atomic context, resolving kernel warnings. Memory allocation is moved outside the lock to support this transition safely. Additionally, a memory leak in the notifier unregistration path is fixed by properly freeing the callback node.
