I don't see it yet here:
http://git.infradead.org/users/jjs/linux-tpmdd.git/shortlog/refs/heads/master
However, I wanted to make sure you captured that this does *not* fix
the interrupt issue. I.e. make sure you remove the "Fixes:
5b359c7c4372 ("tpm_tis_core: Turn on the TPM before probing IRQ's")"
tag.
With that said, are you going to include the revert of:
1ea32c83c699 tpm_tis_core: Set TPM_CHIP_FLAG_IRQ before probing for interrupts
5b359c7c4372 tpm_tis_core: Turn on the TPM before probing IRQ's
...in your -rc3 pull?
