[PATCH v3 0/5] Use tpm_transmit_cmd() consistently across kernel call sites

[Jarkko Sakkinen]

These commits update the subsystem consistently to 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. The point is to make
semantics and error handling across the kernel call sites.

v3: Removed patch that renames tpm_pcr_read_dev() to tpm1_pcr_read()
because it is not mandatory for this patch set.

v2: Added commit that drops externs from all function declarations in
tpm.h as suggested by Jason Gunthorpe.

Jarkko Sakkinen (5):
  tpm: remove unnecessary externs from tpm.h
  tpm: unify tpm_gen_interrupt()
  tpm: return error code from tpm_gen_interrupt()
  tpm: use tpm_transmit_cmd() in tpm2_probe()
  tpm: use tpm_pcr_read_dev() in tpm_do_selftest()
