Pull TPM updates from Jarkko Sakkinen:
 "Features and Improvements:

   - improve tpm_crb behaviour by putting the chip into an idle state
     for each transmission. This improves firmware behavior as the
     kernel now better cancels its state as if it had never touched it
     in the first place.

   - Drop a spurious (but harmless) wmb() from tpm_pm_resume().

   - tpm_tis_i2c now requests the optional reset control and deasserts
     it before communicating with the TPM.

   - replace SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS across the
     whole driver stack.

   - Validate during driver initialization that no duplicate banks are
     received. It's unlikely corruption but since it happening would
     cause oops I decided to retain it as a sanity check.

  Bug fixes:

   - tpm2_probe() misinterpreted a transport error on TPM2_GetCapability
     as the chip not being probed, and the chip was detected as a TPM 1
     chip.

     This can happen in reality only in the extremely rare case of bus
     corruption. Despite the odds, a fix was landed, as it is still
     technically a legit bug fix.

   - It is not really worth the time and energy to go into details as
     tpm_nsc is a somewhat legacy driver, but one null pointer
     dereference bug and another causing use-after-free were fixed.

   - read() of /dev/tpm{,rm}0 with zero size caused a pending response
     to be consumed. Just return immediately"
