Subject: [Regression] Commit "tpm: Introduce function to poll for result of self test" breaks suspend
Hi Stefan,
Unfortunately, the following commit from you:
commit 68d6e6713fcb2ea6278661aaaf5f1c9c821b3751
Author: Stefan Berger <stefanb@...ux.vnet.ibm.com>

tpm: Introduce function to poll for result of self test
This patch introduces a function that runs the TPM_ContinueSelfTest()
function and then polls the TPM to check whether it finished the selftest
and can receive new commands.
Signed-off-by: Stefan Berger <stefanb@...ux.vnet.ibm.com>
broke suspend on my Toshiba Portege R500. It causes the tpm driver to
return an error code from .suspend() on every attempt to suspend the system.
Revertig this commit on top of the current Linus' tree fixes the problem for me.
If necessary, I'll collect more information about this problem tomorrow.
Thanks,
Rafael
