Subject: linux-next: build failure after merge of the tpmdd tree

Hi Jarkko,

After merging the tpmdd tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/char/tpm/tpm_tis.c: In function 'tpm_tis_init':
drivers/char/tpm/tpm_tis.c:193:23: error: passing argument 1 of 'check_acpi_tpm2' from incompatible pointer type [-Werror=incompatible-pointer-types]
  rc = check_acpi_tpm2(dev);
                       ^
drivers/char/tpm/tpm_tis.c:129:12: note: expected 'struct acpi_device *' but argument is of type 'struct device *'
 static int check_acpi_tpm2(struct acpi_device *dev)
            ^

Caused by commit

  e3b975d27b46 ("tpm_tis: Consolidate the platform and acpi probe flow")

CONFIG_ACPI is not set for this build.

I have added the following patch for today.
