Subject: [PATCH 0/1] rust: sync: Add Lock::from_raw for ZST data types

This patch just adds a ::from_raw method to the kernel's Lock type,
which can be used for locks where the data type is a ZST.

The current example usecase for this is rvkms, specifically
rust/kernel/drm/device.rs (kernel::drm::device::Device::event_lock())
