Subject: [PATCH v3 4/5] drm/print: move conditional deref into macro defn
Date:   Wed, 14 Jul 2021 11:51:37 -0600

commit 7911902129a8 ("drm/print: Handle potentially NULL drm_devices
in drm_dbg_*") added a maybe(deref) to 6 macro invocations of
drm_dev_dbg().

Commit 01ff672190bd("drm: RFC add choice to use dynamic debug in
drm-debug") then renamed that fn to _drm_dev_dbg(), and redefined
drm_dev_dbg() as a macro.

That new macro can do the maybe(deref), so the ~9 callers dont have to.

no functional changes. small word-count reduction.
