tpm, tpm_tis: Claim locality in interrupt handler

Browse source

commit 0e069265bc upstream.

Writing the TPM_INT_STATUS register in the interrupt handler to clear the
interrupts only has effect if a locality is held. Since this is not
guaranteed at the time the interrupt is fired, claim the locality
explicitly in the handler.
