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.

Best wishes,
Desmond
