The struct tpm_chip patch partially applied on linux next. I had to
manually change the code. In qemu tpm rng device did not show up on
loading tpm module. My laptop has tpm hw but Linux next did not work
properly in that. All my console were getting spammed with some USB
log message and I could not do anything. X did not start either. I
could not debug the issue as the logs were printing infinitely. Will
get little more time this weekend. Will do a proper test and provide
you the result.
