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
