## Overview

In the Linux kernel, the following vulnerability has been resolved:

tpm: tpm_i2c_infineon: Fix locality leak on get_burstcount() failure

get_burstcount() can return -EBUSY on timeout. When this happens, the
function returns directly without releasing the locality that was
acquired at the beginning of tpm_tis_i2c_send().

Use goto out_err to ensure proper cleanup when get_burstcount() fails.
