Here using enum has been a bad idea in the first place, as they don't
relate in any meaningful way.

Replace the definition with the following in drivers/char/tpm/tpm.h:

#define TPM_MINOR 224 /* misc backwards compatibility */
#define TPM_BUFSIZE 4096
#define TPM_NUM_DEVICES 65536
#define TPM_RETRY 5 /* seconds */

Is 5 correct? TPM_RETRY was 50 before.

And only add this to include/linux/tpm.h:

#define TPM_NUM_EVENT_LOG_FILES 3

Otherwise, this looks good.
