tpm_tis: make array cmd_getticks static const to shrink object code size
Don't populate array cmd_getticks on the stack, instead make it static const. Makes the object code smaller by over 160 bytes: Before: text data bss dec hex filename 18813 3152 128 22093 564d drivers/char/tpm/tpm_tis_core.o After: text data bss dec hex filename 18554 3248 128 21930 55aa drivers/char/tpm/tpm_tis_core.o Cc: stable@vger.kernel.org Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>
