When compiling the tpm drivers as modules I get
ERROR: "tpm_sysfs_del_device" [drivers/char/tpm/tpm.ko] undefined!
ERROR: "tpm_dev_add_device" [drivers/char/tpm/tpm.ko] undefined!
ERROR: "tpm_dev_del_device" [drivers/char/tpm/tpm.ko] undefined!
ERROR: "tpm_sysfs_add_device" [drivers/char/tpm/tpm.ko] undefined!
ERROR: "tpm_transmit" [drivers/char/tpm/tpm-sysfs.ko] undefined!
ERROR: "tpm_pcr_read_dev" [drivers/char/tpm/tpm-sysfs.ko] undefined!
ERROR: "tpm_getcap" [drivers/char/tpm/tpm-sysfs.ko] undefined!
ERROR: "tpm_transmit" [drivers/char/tpm/tpm-dev.ko] undefined!

I added a suitable patch with the appropriate EXPORT_SYMBOL_GPL declarations 
to my testing branch. (also see next message)

Thanks,
Peter
