Subject[PATCH] tpm_tis: make array cmd_getticks static const to shink object code size
Date
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
