Subject: tpm, tpm_crb: fix le64_to_cpu conversions in crb_acpi_add()
From: Jarkko Sakkinen <[email protected]>
commit 49afd7289bd937401c5f7faa193054bc3c41dad6 upstream.
le64_to_cpu() was applied twice to the physical addresses read from the
control area. This hasn't shown any visible regressions because CRB
driver has been tested only on the little endian platofrms so far.
