Looking at it again, I see that the patch does not actually do
what I had expected. As you say the option no longer has any
effect at all, when I thought the tzmem driver would just default
back to generic mode without shmbridge being enabled.

What we probably want here is to change it to

#ifndef CONFIG_QCOM_TZMEM_MODE_SHMBRIDGE
   ...
#else
   ...
#endif

to keep the behavior unchanged and just fix the Kconfig logic.
