Hi,
Following a discussion on the patch ("drm: use the lookup lock in drm_is_current_master") [1], Peter Zijlstra proposed new lockdep_assert helpers to make it convenient to compose lockdep checks together.
This series includes the patch that introduces the new lockdep helpers, then utilizes these helpers in drm_is_current_master_locked in the following patch.
v1 -> v2: Patch 2:
- Updated the kerneldoc on the lock design of drm_file.master to explain
the use of lockdep_assert(). As suggested by Boqun Feng.

Can you pls also cc: this to intel-gfx so the local CI there can pick it up and verify? Just to check we got it all.
