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 */ And only add this to include/linux/tpm.h: #define TPM_NUM_EVENT_LOG_FILES 3 Otherwise, this looks good. /Jarkko
