From: Colin Ian King <colin.king@canonical.com>
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
