Im getting this warning when compiling:

The below patch gets rid of the warning,
but I'm not sure if it's the best solution.
rc = transmit_cmd(chip,&tpm_cmd, TPM_INTERNAL_RESULT_SIZE,
"attempting to determine the timeouts");
+ if (!rc)
+ rc = 0;
}
Good thing that's a void function. ;)
Unless transmit_cmd() is marked 'must_check', maybe losing the 'rc =' would
be a better solution?
what I tried was this:
if (!rc)
printk("test........"\n")
and everything looked good,
but as a soon as I changed
rc = transmit_cmd(chip,&tpm_cmd, TPM_INTERNAL_RESULT_SIZE,
"attempting to determine the timeouts");
to this:
rc = transmit_cmd(chip,&tpm_cmd, TPM_INTERNAL_RESULT_SIZE);
if (!rc)
printk("attempting to determine the timeouts\n");
I error out with transmit_cmd not having enough
functions to it.. so I just added the rc = 0;
and went on to the next.
