An idea how to troubleshoot this?
Can you run git bisect on the changes between 4.11 and 4.12, so that
we find the offending commit? It is probably sufficient to limit the
search to commits that touch something in drivers/char/tpm.
I'll try and keep you posted.
OK I've been able to bisect the problem and the bad commit is:
e6aef069b6e97790cb127d5eeb86ae9ff0b7b0e3 is the first bad commit
commit e6aef069b6e97790cb127d5eeb86ae9ff0b7b0e3

tpm_tis: convert to using locality callbacks
This patch converts tpm_tis to use of the new tpm class ops
request_locality, and relinquish_locality.
With the move to using the callbacks, release_locality is changed so
that we now release the locality even if there is no request pending.
This required some changes to the tpm_tis_core_init code path to
make sure locality is requested when needed:
- tpm2_probe code path will end up calling request/release through
callbacks, so request_locality prior to tpm2_probe not needed.
- probe_itpm makes calls to tpm_tis_send_data which no longer calls
request_locality, so add request_locality prior to tpm_tis_send_data
calls. Also drop release_locality call in middleof probe_itpm, and
keep locality until release_locality called at end of probe_itpm.
