Description Daniel Marjamäki 2008-08-25 10:56:07 UTC
In the function tpm_register_hardware there is this condition...

	if (chip->dev_num >= TPM_NUM_DEVICES) {
		dev_err(dev, "No available tpm device numbers\n");
		return NULL;

Before the return, devname should be kfree'd
Comment 1 Randy Dunlap 2008-09-03 19:24:28 UTC
Shouldn't all of the "return NULL" locations also free chip and devname?
