Hi Jarkko,

After merging the tpmdd tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/char/tpm/tpm_tis_core.c: In function 'probe_itpm':
drivers/char/tpm/tpm_tis_core.c:469:31: warning: passing argument 2 of 'tpm_tis_send_data' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
  rc = tpm_tis_send_data(chip, cmd_getticks, len);
