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);
^
drivers/char/tpm/tpm_tis_core.c:255:12: note: expected 'u8 * {aka unsigned char *}' but argument is of type 'const u8 * {aka const unsigned char *}'
static int tpm_tis_send_data(struct tpm_chip *chip, u8 *buf, size_t len)
^
