Thanks, would this work? I think it's how tpm_tis_init masks during a probe.

static void disable_interrupts(struct tpm_chip *chip)
{
        u32 intmask;
        intmask =
            ioread32(chip->vendor.iobase +
                     TPM_INT_ENABLE(chip->vendor.locality));
        intmask &= ~TPM_GLOBAL_INT_ENABLE;
        iowrite32(intmask,
                  chip->vendor.iobase +
                  TPM_INT_ENABLE(chip->vendor.locality));
        free_irq(chip->vendor.irq, chip);
        chip->vendor.irq = 0;
}
