It's curious that the data size didn't change.

Perhaps you should make sure you do not compile
with allyesconfig when you show these change.

For instance: x86-64 defconfig with this bridge
enabled:

$ size drivers/gpu/drm/bridge/tc358768.o
   text	   data	    bss	    dec	    hex	filename
   9423	    300	      0	   9723	   25fb	drivers/gpu/drm/bridge/tc358768.o
