This fixes a build failure if CONFIG_PNP is set but CONFIG_ACPI is not:
drivers/char/tpm/tpm_tis.c: In function ‘tpm_tis_pnp_init’:
drivers/char/tpm/tpm_tis.c:912:45: error: invalid type argument of
‘->’ (have ‘int’)
acpi_dev_handle = pnp_acpi_device(pnp_dev)->handle;
If CONFIG_PNPACPI is not set pnp_acpi_device is defined as 0 and thus
accesing the handle is not possible.
Fixes: 0dc553652102 ("tpm: fix raciness of PPI interface lookup")
