Commit Message

The driver can be compile tested with !CONFIG_OF or !CONFIG_ACPI making
unused.  This fixes compile tests with W=1 by annotating device ID table
as possibly unused:

  drivers/char/tpm/tpm_tis_spi_main.c:234:34: error: ‘of_tis_spi_match’ defined but not used [-Werror=unused-const-variable=]
