locking/mutex: Don't mark mutex_trylock_recursive() as deprecated, temporarily
Until the DRM drivers are fixed to not use mutex_trylock_recursive(),
allyes/modconfig builds will emit an API deprecation warning:
drivers/gpu/drm/i915/i915_gem_shrinker.c: In function ‘i915_gem_shrinker_lock’:
drivers/gpu/drm/i915/i915_gem_shrinker.c:230:2: warning: ‘mutex_trylock_recursive’ is deprecated [-Wdeprecated-declarations]
switch (mutex_trylock_recursive(&dev->struct_mutex)) {
^
Don't pollute the kernel log until the DRM code is fixed. Hopefully
the checkpatch warning is enough to keep people from using this new
API, and we'll be NAK-ing new users as well.
