This patch set updates the subsystem consistently use tpm_transmit_cmd()
throughout the subsystem the exception being tpm_write() where it makes
sense to use the raw interface because higher level command handling is
delegated to user space.
Jarkko Sakkinen (5):
tpm: unify tpm_gen_interrupt()
tpm: return error code from tpm_gen_interrupt()
tpm: use tpm_transmit_cmd() in tpm2_probe()
tpm: rename tpm_pcr_read_dev() to tpm1_pcr_read()
tpm: use tpm1_pcr_read() in tpm_do_selftest()

Migrated into single tpm_gen_interrupt() function and cleaned up the
whole construction in general because it was starting to turn into a
train wreck.

Return error code from tpm_gen_interrupt() and fail tpm_tis family of
drivers on a system error. It doesn't make sense to continue if we
cannot even reach the TPM.

It is better to tpm_transmit_cmd() in tpm2_probe() in order to get
consistent command handling throughout the subsystem.

Dropping the argument name is not the kernel standard, if these lines
are going to be churned they may as well be churned to the standard.
FWIW, all the extern's should be dropped too.

Thanks for pointin these out. And yes, since this is mostly a cleanup
series, adding a patch that would clean up those unnecessary externs
would make sense. I'll send a revised version with your suggestions.
