I have found three instances, the one in bridge/synopsys/sw-hdmi.c I
checked and the log msg of commit c2a441fe8f7 mentioned that an explicit
assginment to the best_encoder is needed because the bridge is compatible
with both atomic and non-atomic devices.
I suspect this is the same case for vmwgfx/vmwgfx_/ldu/scrn/stdu.c from
checking commit d947d1b71.
Lastly, there is an instance in tinydrm/core/tinydrm-pipe.c but I am not
sure how to verify if the driver supports atomic and non-atomic devices
as well, hence justify deleting it.
